while playing some combo decks time is not enough, like infernobles. Yesterday I couldnt activate charles at the end because there was 3 sec left. Its especially bad when there is a bit of lag, timer run out near the end. (I do know the combo full and I am trying to play as fast as possible)
I do know that increasing the timer can also cause problems but without a change long combo decks are hard to play because of timer concern
