I realize there are other even more problematic ways that players manipulate matchmaking to increase/ensure their odds of victory, but I'm wondering what people think about this "strategy" I've seen. There's one particular pair of players that I'm often matched against (and occasionally with) in ranked. They always queue as an ele and a thief (two of the weaker/more specialized pvp classes for mid-tier ranked) and swap to warrior and guard (two of the strongest classes at that level). They are obviously doing that to try to manipulate the comp of their team to be stronger teamfights, especially if they manage to get 2 eles or 2 thieves on the other team. They win most of the games I've played with them, I'd say maybe 80%.
I guess there's no real way for ANet to judge intention, so to stop this they would have to prevent class swapping altogether. I'd be fine with that, but I'm sure a lot of others wouldn't (and it would prevent solo players from trying to swap out of a genuinely bad comp). What if duo queue players cannot swap but solos can? Would work for me too, but again I'm sure others would complain.
I think that being able to deliberately manipulate 40% of a team comp to try to take advantage of the matchmaker adds an additional unhealthy advantage to duo queues. What do others think?
