It's a 1 vs 100 and you'll win MMO. So easy. The ONLY redeeming thing about it: You don't auto regen health. You need to find a camp fire in town or have a cleric/healer in your party. Because of that, you don't take a lot of damage per mob.
The user created missions will troll you. Like you are told a story, put into a dungeon/map, and there is no way to complete it. You try for awhile, then realize they are giggling at all the stupid folks who tried their mission and failed to complete it, and exit out. Too many people don't even bother with user created missions.
Not to mention the network engine is horrible. Go in town and it's a warp/lag fest. The network code is very bad and can't handle any amount of traffic, so each area is a 16 player max instance. More than that, and it will spawn off new instances. So it's not really "massively" at all. It's 16 people max.
I got to about lvl 20 before I gave up. It felt similar to Rift but even more easy mode. I'd rather play Rift.
