If you hit lvl 120 on one of the new classes within the next week or so I think, you get some decent gear for your char that's a really good start for someone unfunded.
Kaiser is a really good class, totally overpowered, wicked training after level 100 at LHC due to massive damage output.
Angelic Buster has similarly wicked damage output, but the whole recharge thing gets tiresome and annoying pretty fast, but they do have seriously ridiculous damage.
Luminous is a mage. Mages mob well. Mages suck at bossing. They're stronger than the other mages because they're new, but it's still a mage class and is designed for easy leveling until 100, which you hit so fast I just don't see the point.
Either way, I have a level 200 AB and lvl 180+ on the other two and I'd say Kaiser is probably my favourite for bossing but AB is sweet for training.
