I understand that my position means my actions and words aren't without consequences but my opinions on the game design aspect of the game, as strong as they may be, have yet to influence the ETF2L admins to my knowledge. In this case, this "trick" was presented to me by ETF2L admins and I was asked to see if it was possible to patch out, so I imagine that they already had their mind set about it.
I'll accept a PR rewording the description, or I'll get to it next time I can work on the plugin.

Just to be sure, what is referred to in that sentence is the process of popping uber, picking up a medigun from the ground, which cancels your ubercharge, and then picking up your original medigun, in which some undercharge percent remains
I decided to call this an exploit because I believe popping uber is a commitment and that you shouldn't be able to cancel, exploit might be a strong word.
It does take some skill (and luck) to pull this off, so it's not like the game is worse off with it.
I guess admins should have a quick look to see if they'd rather enable it or not, they should ask ETF2L admins for a demonstration video.

ANN:

v1.14.0 of tf2-comp-fixes adds `sm_fix_post_pause_state`

E: This is similar to the feature of the plugin by F2 and maintained by Aad used by RGL, this is mainly because ETF2L wanted to enforce the feature without having to require installing another plugin.

v1.15.0 of tf2-comp-fixes adds `sm_solid_buildings`, `sm_empty_active_ubercharges_when_dropped`, `sm_prevent_respawning`

Sorry for the double post

The IB fix ( ;) ) is a feature of the plugin. The plugin, which is a collection of features, is already required by all major leagues, and they don't all make use of the same features.

You're comparing a change in the game that does not affect conscious decision making (you're still aiming and dodging pipes the same way) and the settings that rule the entire gameplay flow (win conditions).
Can you see that the first one is pretty much not making a difference?

Also, if this was so important, would have whitelists diverged? I believe there was a point in which every league used the global whitelist.

All major leagues already use and require the plugin.

Let's consider solely the cases in which you see an IB pipe coming, maybe you manage to dodge a little, it looks like it might not hit you but does anyways, I imagine that's what is inducing frustration in players.
Obviously, the solution here is to keep your tilt in check, but because the cat is out of the bag and everyone knows that the IB pipes are bugged, it's much harder to rationalize those situations.

fair fair

I don't have a massive math brain but I have a hard time considering those funny equations, I'm not seeing complicated integrals anywhere, which I would expect considering the game simulation happens over time, and in 3D.
It feels like an easy way to either make it seem like the difference is small because the resulting number is small, or the difference is huge because number is huge.
Even the difference in volume is not properly evocative if you forget/don't know how volumes scale.

If you really cared to have a good measurement, I think Pheaa's got the right idea about it: "I would love for someone to create a plugin that checks if an iron bomber pipe that hit would have hit if it had the stock hitbox."
However, you could only easily find which default-sized pipes would have collided if they were IB-sized, so either with the resize feature already enabled, or by checking non-IB pipes (which may skew your data, as people mention that IB pipes are harder to spot mid-air, so harder to dodge). This is potentially a resource hog.
You could find the opposite if you managed to simulate the game as if IB-sized pipes were actually default-sized, and check whether they would still collide over their lifespan. This is pretty much only feasible as post-processing analysis of demos, and a huge amount of work.

At this point though, it feels like we're doing a lot to find whether a bugfix should be applied or not, is this the right criteria for inclusion?

Obviously, can't do anything about pubs (do you really practice in pubs?), but for MGE and DM, this is something that can be fixed, if it's not already fixed, talk to the owners.
This is the only point you manage to make in all of this post.

This sentence especially sucks considering you hardly manage to put into words what you actually think. I don't deny that you have more experience and understanding of the game, but extracting any of that through your posts is literally impossible, they critically lack any substance. That was also the case when giving feedback about the medic attach speed tests/season!

No hard feelings, but you can do better.

ANN: v1.13.0 of tf2-comp-fixes introduces a cvar to inhibit `extendfreeze`, I invite league admins to consider adding it to their configs. The update has been deployed to serveme.

Here's a demonstration of the info leak, at 6:10

Thanks to JackyLegs for bringing this up to me

There's a lot of variable settings that leagues make use of and I don't see complaints about it?

I'm not sure if this is established in the current conversation but it might be worth mentioning:
The plugin allows overriding the dimension of the hitbox (which is forced to be a cube) to any value, 4.0 being the one of default pipes, buffing all pipe launchers to be as big as IB is a possibility, so is finding a middle ground

Now that I think about it, the cvar should be called `sm_override_pipe_dimension` :(
(IB pipes are over 9 times bigger in terms of volume hehe)

Would you make the point that using this feature introduces potential differences between regions? I don't buy that, banning a weapon has the exact same effect, the difference is that the plugin lets you play with the weapon, which is a positive in my book

GitHub user bodolaz146 did implement this actually, but yeah it was ready for ETF2L S40

the only thing ur holding is this fat L

those build tools are all dog shit.

Here is an update for tf2-comp-fixes, v1.11.1 is probably very broken
https://github.com/ldesgoui/tf2-comp-fixes/releases/tag/v1.11.2

Sorry for the delay
