I agree though I'm not convinced that it should be exactly the same as SWBF1 HvsV.
I would love to see it go to 6v6 or 8v8 but have everyone in there playing heroes. I think the hero pool needs to grow and people need time to unlock them first but currently there are 14 heroes, and about 9 or 10 of them see play while there is no point in unlocking the final 4 or 5. I'd love to see HvsV go 6vs6 and have all the heroes unlocked for this format only. We might even find a hero we like and it may give us incentive to unlock it.
