I think the main problem here is not just Wedge + Biggs, is the whole game balance. It sucks deeply. Most chars are useless and the competitive ones are a nobrainer. The only way they find to push players away from an OP meta is creating another OP meta with even more OP chars instead of properly balancing things. It just make things worse and worse in the long run.
But the worse part of it is to come here to the forum to see players saying things like "just run team X against them". So that's it? I have a game with a lot of chars but they are just fillers and an illusion of choice? If I don't play the game a very particular way with very particular chars I'm doomed to be sideshow forever!? I know the game have other play modes than Arena, but mostly all of them are also a PVP or just grind so you can perform in the PVP modes; like the GW when you do face other Players, tournaments where you do face other Players and Raid where you compete to other players indirectly.
And judging of how bad the game balance is now and how they keep making it worst be creating more unbalanced characters instead of balacing the ones that already exists balanced, I have little hopes for change. Maybe the people who says it's too late now are right, the amount of balancing this game needs is almost a reboot and I don't see it happening. And to make everything even more sad: some of the OP chars are random guys from the Star Wars universe while some of the useless ones are actually fun, powerful and famous chars amoung the fans. I like the game the way it is, but it could had be SO-MUCH-BETTER if the devs was just a little more competent in the balancing.
