Got together with 5 mates tonight to play some customs and gamechat is very inconsistent, in the lobby before the first game everyone could hear me except for one player then we went into a free-for-all game in H2A and no-one could hear anyone. When we returned to the lobby the player that couldn’t hear me before could but now a different player couldn’t hear me and another player. Then we went into a team game with the opposing team of 3 claimed no problems whilst in my team two of us could hear everyone and one could hear no-one. When we returned to the lobby some players could hear some player but not others etc.
In the end we went to party chat which is not ideal if you want to play team games or play with more than 8.
Gamechat has been pretty awful across all Xbox One titles since launch forcing you to switch to party chat and considering very few online games allow custom adversarial matches I think a lot of people don’t realise just how bad it is.
Hopefully one good thing to come out of this fiasco is for Microsoft to fix the chat issues on a system level.
