Solar, thats great, but will it make high tier shotguns more usable? The dominating builds are BG (Minigun, Rocket(support most probablly) snipers (Lazer/SG sniper) and that's it, oh yea, almost forgot, burst P90 and grenade builds (less common due to their disadvantages and mainly their cost) meely is dead, and so are shotguns. If shotguns were good enough, I'm sure that people would use them much more than now (right now I encounter mostly BG builds and some snipers)
I seriosly think that boosting some unpopular weapons would add variety to the game, because a build is always based on gear, more usable gear-more builds-more variety.
