I think they know they have no hope in hell of conquerer levels/esp with the patch.

Let's face it there are a lot of +10 folks here that went thru a lot of pain to get there.
Wiping exp would be like slapping them in the face and in 90% of the cases will be the final straw that pushes them out the door.

for exp needed to get to +50... I think 900x times 5 (900x being the amount to get 10 conquerer levels) ... 4500x would get you there.
That would take a sh!tton of leveling to get there and I don't see any place in this game giving that level of exp (remember you stop getting exp from mobs when you go ten levels beyond them). I mean there are no level 155 or 165 mobs around. I hope they are not intending the only way to level is via PvP. That would suck monkey turds.

Will be interesting to see how they intend to pull this off.
