CCP please consider buffing many things in the game instead of nerfing them.
Not exactly sure as to what i'm saying is true, but i wanted to point out that the people asking for nerfs aren't really needing nerfs. Maybe these people aren't looking for a fair game but they're looking to increase enjoyment in their game experience even more for the expense of making the game experiences of everyone especially newbies into the game.

Plasma Cannon - Increase splash damage radius. Why? It's an awesome sounding weapon, make it do something nice. If it's found to be too strong increase the splash radius, keep head on damage the same but lower the damage based on distance from centre.

Having guns which aren't good 1 on 1 like the plasma etc should be doing spectacular in team engagements, for example. A plasma cannon could definitely not take on a moving target with a high dps weapon but it will give the other team the advantage of crowd control as it wreaks havoc amongst a squad. This also emphasises squad play as the plasma cannon user can be escorted by the squad just in case they run into another well operating squad...
