Prof forces gtb more than priest. Almost all gang fights have a prof these days. With everyone wearing gtb Priest is just a useless target. At best its a distraction, at worst its a free kill. Soul linkers are always going to be hard to balance, but priests have always meant to be the best support in the game. Soul linkers can cast that revive skill outside of pvp and enter with it, we priests can't cast basilica outside pvp and warp in with it. Basilica is about keeping your party alive when they enter and a counter to people who just get gospel, run in, and mess your entire crew. There are many ways to take it down so I don't see how it's imbalanced. Soul linkers can't use their revive skill for obvious feeding reasons. Priest has resurrection taken away, why remove basilica? PvP is almost entirely offense-based on this server (who can do x amount of damage the fastest). There should be more defensive play and basilica is defensive play at its finest.
If saving your party and trying to keep them alive is "abuse" we might as well remove devotion as well.
As for the other suggestion, like I said: I'm agreeing with you on this one. I just don't think its fair for you to assume that just because people might disagree with it means they promote feeding.
