Momentum shift - late game turn arounds don't happen
The outcome of most matches is pretty much determined well before the round actually ends
What I'm talking about is the outcome of a game being set well in advance of the actual end of the round. Turning the momentum of the game back around in the other direction is really rare to see. I'm a little irked to see that this hasn't really changed from other AoS-style games/maps.
Momentum I sorta see as the composite of average rate of gold gain and rate of exp gain. There are frequently in-game events which trigger an elevation of one teams strength to the point where their momentum is impossible to overcome. For example, one team has pushed forward far enough to hold vital flags in the middle, making it extremely difficult for the losing team to flip those flags back over without overextending and getting ganked. Or maybe one of the enemy DGs has amassed enough gold for one of the decent artifacts, and with this new edge is able to outlevel and constantly force you to fallback and heal. The time wasted retreating and healing only further exaggerates the differences in gold and exp rates.
And because of this, the fate of the round is frequently determined by these type of events. But the problem is there is still 10 - 15 minutes of gameplay left (maybe even more; take for instance when you have an inexperienced teammate who is feeding early game... disasterous). Maybe domination mode overcomes this problem a little, but I still feel like it things could be better. I really LIKE conquest mode, but find that it is most prone to this problem.
Players with good etiquette will stick it out and finish the round, but it is a very trying experience because you know fully well you are going to lose. Maybe adding something like a 'Concede match' vote? After x minutes of gameplay, players on a team can initiate an in game vote to concede the match to the other team.
Or maybe there is some really great way of buffing the losing team to actually facilitate late game turn-arounds. It would certainly add to the excitement if there was the possibility of a late game upset. I don't think this is an easy problem to address, since AoS maps have always had this problem, but I'm sure there is SOME way to improve.
