Just had a try with someone from the Opvp channel, and Engineer in a fleet escort vs my engineer in an assault cruiser.
On thing that may not come as a surprise, but I want to mention it nevertheless: Even with a build highly optimized for boffless (numiri shield array, 2 shield amplifiers, 8 phaser beam arrays, 3 phaser relays), I did not really have a chance in my cruiser, as he simply out-dpsed any shield regeneration before I could out-dps his.
Still a fun way to fight, though. One just would have to run escorts against escorts, because any other type of ship just won't keep up with them.
Eliminate all abilities including captain abilities. Fly with no tray. Just shoot, fly, distribute shields and power levels. You could also take this to another level and only allow certain tier ships such as tier 2. This can work with any tier ship even mixing tiers if you have enough players to balance it out.
I started this post and was about to mention the large supply of Coke's and Gladiator movies I have in my ready room and then I realized that in my haste I had misread the OP as "topless PVP 'and now I realize all my hopes are dashed.
Well if anyone starts a topless PVP thread I'll be sure to chime in.
