Just a thought that I had back when all those shuttles started popping up in STF.
I thought it would be interesting to be able to add options to PvP for ship tiers regardless of character level for those who want to have a reason to bring out some of their old favorites. A little drop down or check box and give the person creating the game an option for what kind of ship can be brought in. You like tier 1s and want to bring out your NX and Connie replicas? Awesome!
I was thinking of this in the Mirror event recently. My VA and LG both have Galors, and can just kind of wade in and start blowing things up, and even tank the ship at the end (who's name I forget at the moment). But my lower level Fed who is in a T2 Cruiser and my Klingon in a T3 BoP really had to fight those mobs, and that lower level action was just plain more exciting. So the option to run that in PvP could bring some much needed life and excitement, especially for F2Pers who don't want to "Pay to Win".
