I would like to have the good old-fashioned blue Plasma Rifle back. I don’t think a color swap and fire rate change would be too difficult. Hell, I’d be happy with just a color swap.
The old one looks nice, but the fact they have one in the game already, I cannot see much point.
They could add a slowing effect but slower fire rate to the Elite Plasma Rifle. It slowed you decently in Halo CE.
Great idea however as Trusssson stated although it is a reasonable request it just isn’t likely they will add it into the game. However we can always hope!
