Ur right, its kinda dumb for riot to allow coaches to talk in team chat, but to be fair to them u could make the same argument for all the bugs in the game, "just know the problems 4head" even though this is an obvious problem.
Even then this whole online games thing is very shady, u could talk on any other chatting service on another monitor.
No the bugs that aren't supposed to be used are already listed for the players bro. That cypher cam bug from VK v ACE was already in the rulebook. That's why they were penalised.
And as for the coach thing, there's a really simple solution if riot is willing to implement it. Just have the coach stream his facecam POV during the entire match. Riot can then have it for reference in case of any discrepancy.
