I'd actually say for Wildstar that leveling is a learning curve. If you play like you do 1-15, the level 15+ zones will chew you up. I just wish that the game focused less on trying to force you to group up for things, between absurdly fast regenerating Interrupt armor and quests/challenges being difficult to Gold without kill tagging it's a pain being a solo player, especially as I'm not an Engineer (Pet taunt op nerf).
