timer too long
Turn Timer!
It's no secret that users are just starting matches and going AFK in an attempt to purposely waste time and just hope the opponent get sick of it and Forfeits. Do that all day long while you are at work and boom you have your 15 wins for the day! In extreme cases users do their absolute best to get through a match completing actions at the last possible second so they never lose, and the matches takes 20 minutes if you want to stick it out and Maybe win. Most ppl just FF.
I propose major timer changes for the beginning of the match. There is very little to do besides play a land. You should have about a quarter of current allotted time to start the game with. Make Players pay attention, or lose. The turns are so long timeouts are not even necessary. I think the turn timer should be very short, and if you have earned your timeouts then having them when needed is would make sense. They excessive amount of time given per turn encourages players to drag everything out, not pay attention, intentionally go AFK in retaliation etc. and they have 3 timeouts to boot.
I really enjoy MTG Arena, honestly would never play magic without it. But the number of users abusing matches makes me not want to play. and I'm a paying customer. Something tells me the trolls are not spending any Money;-)
