Agreed with Killjoy for the most part.
Anything to put more variety in the game : several guns to level with, several mobs to level on. (as people said above : make XP based on damage, not # of hits, and make common monsters -not
easy, common- give more XP).
Sticking so strictly with gold standards as how it is currently is not good, cause it induces the same old needs for "leveling exploits" (ash hill, stacking elders in BM, stacking rancons in catas, ledging eyezion... who the hell REALLY never used ANY of those ?... Xplosive, i forbid you to post anything here :-D)
So yeah, now for instance, i can't ledge eyezion anymore. That was a fun process, sometimes i would die while he was coming to the ledge after i pull it, sometimes i would get PKed and the "spot" would be stolen from me... Of course, that used to be only a few minutes amongst the dozens of hours i spent there, semi-afk leveling.
Anyway, that's no more possible. And stacking monsters is no more possible. And almost every runebosses (exploitable) XP has been nerfed.
You guys have been fighting AFK leveling all along, which is fine, but you didn't change much things about the reasons why so many people afk-level.
You keep comparing the game to others where "you also have to level for hours". Well in other games you have to change your leveling spot many times all along the way. Not in EA. In EA we're talking about acidgunning the same freakin mob (highest XP you can find. And that's not "missing out on the game", that's what any player does in any game) for your entire leveling life.
So right now i'm looking at 50 hours of spinning around eyezion on kidion mount, slept away by the "pfft - pfft - pfft" of the acid gun. And i'm yet to find the courage to do it.
I say if you wanna revive gold at all costs, you have to revive the leveling exploits, too. And since that makes no sense, you have to go for Killjoy's point of view, imo.
Back when people were discussing about the leveling rates, mob stats... etc... in the new EA, i was hoping for devs to find a "happy medium" between gold and booster. Well that's a bit too much goldy i think, at least about leveling.
edit / disclaimer : that's only my "2 cents" (i never understood this saying btw

, but if that means it's my opinion which is worth 2 cents, well yeah that's exactly it)
