Broke down and got this to give it a try.
My biggest complaint so far 5 character slots and $10 for more is a ripoff, I can't even try each class without deleting a character
But it doesn't take long to get an idea of each character, and I'm already in trouble because I pretty much everything so far lol.
Started out with a Necromancer to express my inner gothic lolita but don't really like it, not usually a fan of classes with pets. But every other class I've tried is neat. Warrior you have so many weapon combinations it's crazy, couldn't see getting bored. Elementalist is the same with magic. Thief is fun with the pistols and the back stabbing.
So far I just like that there's so much variety within a single class, and then the different classes aren't just copies of each other class's variety; they're all very different from each other.
The level up/down for content is also interesting.
