Well, it's not imbalanced, because everyone is grouped into level blocks. It's kinda crap that we have to get to almost half way to use the lights, though :dry:
Its really not that bad. If you think of the level curve from Guild Wars, level 7 came very easily. Tbh, if you were fast enough, you could hit level 7 in 30min or less. If you were hardcoe like me, and picked up all the quest in the Factions Main Town... you would hit level 20 (the cap) in less then 6 hours (granted the end curve starts at 13-14 usually, right when you're able to pick up said quests). Ive done it in 3 hours. (
The end game is not when you hit 20)
Brink's leveling curve shouldn't be as easy as this, since its pretty much fixed. In GuildWars you could pick up a bunch of quests, complete them all, then turn them all in at once kinda thing just like WoW or most other MMOs.
