Guys, I don't think you understood the OP message; and I have his same issue and believe most of you don't have it because you are above the gold tier. Lemme explain:
The matchmaker puts you 4 guys in your team and 5 in the enemy one, hopefully all about the same skill range, yes, correct. But why do most of the matches look like one team is trashing the other one like they never stood a chance from the very matchmaking process?
In the "elo hello" like someone called it, by minute 12 (left in match) you can already tell which team is going to win; this is what the OP is wondering and I can confirm. In the best of cases and the win chance is literally 50%, shouldn't then the score of the match go somewhat 50% for each team? Why after the first three of four battles the score goes 80/20 %?
This is beside the skill issue, top players, AFKers, etc. both teams have those and the matchmaking says both team are almost equal in terms of skill; then why one of the teams end up stomping the other one like they were way superior in skill, top players, etc.?
The other day I played a tournament, my first one, and I was like "this week is PvP rush, there are going to be a lot of noobs to farm". Ended up against two teams of players that started the match saying "gg, bad luck in the matchmaking, GL next time. Happy leg farming!" before the first fight and went spawn camping us mercilessly. I assume that was actually the matchmaking problem...? Well, this is not what this thread is about.
I'm new to PvP so I cannot tell, but the OP seems to be more experienced and still has this imbalanced teams skills issue; and the lower you are in the ladder, the worse it is. I wonder if there could be something we could do that we are missing? Coz sitting semi-AFK knowing the match is lost and the enemy team still hasn't reach the 250 score feels a bit odd. If there is actually a way to fight for the win of a match that just started but already looking lost, please let us know!
