I'll try to address a few things here
Nobody wants to go to the trouble of organizing a global whitelist meeting every season, including myself. Sorry if I'm stepping on the toes of other leagues but at this point I feel that the global whitelist initiative does not have a strong impact unless we do things like unify rulesets, maps AND make controversial and aggressive changes to the whitelist rather than just have the same perfunctory weapon bans each season with a few tweaks. I'm not exactly opposed to the above but that's a topic for another time.
The invite meeting was held at a time when we did not know how many invite teams were alive or reforming. I need to submit changes such as map changes and whitelist changes before the season starts (i.e before the registration deadline). I realize that this is somewhat circular reasoning as clearly there were more opportunities to get more substantiated opinions from invite players, but since a lot of invite teams died and we did not know the status of the division (like every season), I was more worried about getting the invite division together, and I really did not know that there would be a reg extension (the extension was due to some issues causing players to not be able to pay their fees).
So that's why we addressed weapon bans in that meeting. That being said I attempted to make changes that everyone present had not only universally agreed upon, but also agreed that they were fairly inoffensive choices. Regarding map bans, there was very little agreement on either which maps should be removed (except that most wanted badlands out), or which should be added. The community map vote was not very helpful as there was strong sentiment for keeping badlands in.
Rescue Ranger: it's still banned.
Cow Mangler. With respect to the original global invite whitelist meeting where we decided to ban it, IIRC it was not something that was strongly agreed upon and the reason behind banning it was that it's a straight upgrade without enough of a downside (rather than being strictly overpowered). I know that a lot of people think it's overpowered but we did discuss it during the meeting and no one felt that it was worth leaving banned. The two upgrades on the item are the infinite ammo and charged shot. Maybe someone has pushed or won a fight off of low ammo counts at some point, and there are some strategies involving the charge shot for area denial. I don't think that either of these mechanics are overpowered.
Skill expression: Ammo management is not an expression of skill or team coordination. If it is, it is not comparable to something that is an expression of coordination AND has a strong impact on gameplay, such as damage/health callouts (referring to the Solemn Vow allowing you to see enemy health).
Closing remarks: Please direct your hate towards me instead of b4nny or any of the other attendees of the invite illuminati meeting. I'd like to express some of my frustrations too. I think the best method would be a global vote among invite players/teams, but that cannot be done if I don't know what invite teams are even competing until practically the last second. anyway thanks for listening
