Yeah, implying one team that chooses a coach to maincall would pick a retard who knows nothing about the game. When you choose a coach to maincall, I guess every team is going to choose wisely, no way you wouldn't benefit from it.

Some teams have been formed and sometimes not a single player among those teams was a maincaller. In CS for instance, the brazilian team Tempo Storm (now Immortals) had no IGL, which is why boltz decided to take over the IGL duties in spite of having little experience in this domain, and he did great (zews is the IGL now, but boltz did lead for some time). Same goes for FalleN actually I believe, and he's the best IGL in the world.
I might be wrong here, but I even wonder if kaidus' first time maincalling wasn't with BFF in season 14, because until then he had been on teams with established maincallers (Zebbo in season 13 BFF I guess, probably Byte in TCM...) I did some research but can't confirm my claims so perhaps the man himself if he reads me can tell if I'm in the right or not.

Kaidus might have built something with Crowns before he had to retire, but when your maincaller leaves, either pick a player to replace him who has maincalling abilities, or have one of your current players become the maincaller. It's not impossible, it takes work, and a lot of dedication (and a bit of talent), but that's how it should be, that's another component of the skills you have to possess to play TF2 at this level. And you can't just rely on an external person to do this work for you. Like fuck, Epsilon had numlocked and KnoxXx, literally both of them were maincallers, don't go telling me not a single Crowns player has the gamesense and knowledge to actually maincall, to pick up from what Kaidus left behind him.

Maincallers aren't born, they're made, that's why in my opinion coaches shouldn't be allowed to maincall. However I have nothing against coaches if they do their work outside of the game.

I don't know, I can see there being so many cases where a great main caller has improved teams ten fold and not having to worry about doing anything but calling seems like such an advantage.
You could cycle through an entire team to see everyone's health/positioning and numbers advantages during a fight and accurate comms could definitely make or break certain fights. I've also heard really good calls come from players who are dead and can keep an eye out on all that. We haven't played with a coach to know the full potential.
Yes most teams can track ubers but I've played many matches when a call was incorrect because an element wasn't accounted for. "Oh we did get their med?"

Having a coach just cheapens that all in my eyes.

For the record I really don't care who wins this tournament I just really don't like coaches being introduced this late in tf2's cycle when it's not even a feature of the game. The anti-valve.

One good example is Crowns LUL they lost to some shitty prem team on viaduct last season after picking up spudd

Wait what is he doing that is considered unfair?

Only admins are allowed on the server to spectate unless opponent agrees, having some guy sat behind you or on a chair next to you or on mumble watching some sort of STV with minimal delay isn't against the rules and if a team wants to utilize it, good luck to them.

and they went on to switch kaptain and stark to moderate success at DHS
