Before they can put in an adequate way of leveling they need to revise the battle system, and they're revising the system because a majority of people want it that way. Once the battle system is in and they can start working on the grinding mob aspect they might get rid of it if they ask the players if they still want them, but we will have leves for a while, though you can actually grind on mobs more efficiently with a group of 4 in Coerthas from 30-50. I honestly don't see why people feel that leves are the only way thus far.
