I'm getting ready to make a character for the upcoming AoR that our GM is going to be moving too and I and mostly doing it from rules in EotE. I'm envision him as Roadblock from G.I. Joe (the huge heavy weapons guy from the 80's cartoon - rhyming) but as a wookie using a heavy repeating blaster.
I'm a little worried the GM may find this to be a little over the top / no possible. I'm looking for some kind of precedent in the Star Wars universe of a character using a weapon of that magnitude.
