Skybolt seems a little weaker now, which is great, although I still don't think many people are going to be using it. As for the plasma, fix that bug asap! I can see it being used for little boosts on cap routes as well, so that will be interesting to play around with. I agree with Fixious about the blaster/burner using up energy rather than ammo (more variety within the game etc), but I must be failing to see the purpose of it. Mortar seems great though and the grenade changes could be interesting, after awhile when everyone gets used to them.
Hand Grenades now look pretty crappy now, and although I can understand the reasoning behind (two different colours, two different grenades) they still look cheap and legions now looks like a multicoloured rainbow.
