Quit...though that might be happening soon enough as the same canned pvp maps are getting terribly old. I'd love to see some type of RVR introduced but don't think it will happen.
A single sector of all tier FvK PvP with big signs saying "Here be PvP, enter and you will DIE!" What's so hard about that? No rewards per se, but allow the "kill X number of enemy captains" or "die Y number of times in battle." Just plain FUN!
So what if a big bad tier 5 smoked 20+ tier 1. You should expect that. The problems as I see them - unbalanced numbers; instancing only allowing a few dozen players; no ability to pre-group.
So, establish a "waiting room" (call it a fleet assembly area) and everyone from Fleet whatever goes to the faction waiting room in instance X. Run the thing on a timer - 20 to 30 minutes at most. Maximum size 20 per side with no more than a 2:1 advantage. Have both a faction and individual kill counters. (It was called "Castle Wars" in *********.)
