Welcome back to Allods,
This would be more suited to the "
Archetype " forum - where you can check out/ask for the latest class info (assuming any existing guides have become irrelevant due to 8.0).
Stat wise, it's a lot more clear-cut than it used to be, and the basics can be checked by mousing over the statistic in game. Proficiency being a flat-increase to dam/healing, Bloodlust being healing-through-damage (vampiric) etc
Unlike the past, builds and stats have become a lot more streamlined and compact, so you should have no problem getting to grips with them.
Regards,
Mhul
