Naa yo, you seemed hype for it. Like I said, I prefer to keep my mouth shut about the game because if it's your cup of tea, then be hype for it. Don't let me be a downer for you. I play all sorts of games and get hyped over stupid things all of the time. Like the Civilization MMO -- probably going to go horribly but I'm still going to give it a shot.
As for the ability to respec easily, that's become fairly common in RPGs and MMOs. After the days of Diablo 2, developers started to notice that players hated to be utterly fucked if they didn't plan out their build thoroughly from conception. Haven doesn't exactly lock you into anything though as learning points aren't restrictive; as in, there isn't a small pool of learning points that you'll get from leveling up and that's it, those are the only skills you can learn. It just takes a bit of time to buy up points in another skill, though that's fairly common to do once you're established and no longer just scraping by. Most UAC fighters start to pick up MC, crafters diversify their points into the other crafting skills, and some people like me just buy all of the skills up because lp is cheap and death is so easy to avoid if you know what you're doing. Besides, I hate juggling alts to do every little task.
