I'm only a casual PvP player, so take my feedback with a grain of salt.
1. Really like the style of RV. Open warfare with a point makes for good interesting PvP.
2. Things were a little too deadly. A group of 4-5 minions could wipe a team of heroes, esp. since they can arrive without attracting too much attention.
3. Named characters were far too hard to kill. I was in a protracted battle against Positron that went on for the better part of 15 minutes, involving no fewer than 20 heroes. Once, he dipped below 30% health. Once. For about 2 seconds. Silly. If it's not meant to be defeatable, don't let it be targettable.
4. Reinforcements. It seemed to me like the reinforcements went to the pillbox that was just taken. I would think they would run to an unclaimed pillbox (or one controlled by their side if possible).
5. Maybe it was the lag, but I felt that SS and SJ were making the drive-by tactic too effective. In PvE, the delays for drive-by attacks were balanced by the speed of the computer's response. In PvP, the delays imo need to be corresponding larger.
6. Stunning is a one-shot kill in PvP. Dropping toggles is fine, but I think Stuns in PvP should be virtually zero length. Even if multiple powers are used, Stun + Attack = Death is still a one-shot kill in my book.
