Finished the beta, even did the extra island they added later. Hard mode didn't provide any challenge whatsoever outside of the very first fight where you are just plopped into a very disadvantaged position; and a very few damage spikes that literally one-shot one of the party. I didn't rest once throughout the whole thing and it's my first time playing through it. I also used Empower exactly once on the Priest. Make of that what you will, I ended with only 3 people having a single wound each and that's due to the aforementioned one-shotting. Writing is WM level, as in short and concise, which is fine. The combat, however :X I decided that, while it's not too fast and I won't mind if they don't slow it down, I won't mind if they do slow it down either. Spellcasting is not too slow, but I do think casting damage spells is not a good idea in big fights, it's better to cast other things. It's a combination of having enough damage already, them doing not-that-great damage and being more beneficial to cast CCs and such.
Outside of specific class design, which I don't think is good, it wasn't good in 1 either and I think it's worse here, the combat's main problem is the unreadability of what is going on. I don't know if that's because it's too fast or the UI is shit, or the models kind of clump together and it's hard to see what is going on, or a combination of these, but it's simply undecipherable when a battle is big enough. And this is only on 5th-6th level, imagine what will happen when more things start vying for your attention. Multi-classing is the way to go, I don't see a single benefit to going single-class, you just choose to gimp yourself if you go single-class. My Shifter would've been half as good as he is now without the Rogue levels and abilities. ESPECIALLY as a Shifter since you spend 95% of combat in forms and you can't cast anything, so going single-class Shifter is literally useless because you can't cast spells in the forms and having more of them is equally as useless. A lot of class combinations aren't very viable as a Shifter, though, because a) you can't cast spells in the forms, so no spellcasting multis and b) a lot of melee bonuses from other classes don't work in the forms, like the Monk unarmed bonus or any Fighter bonuses to weapons. You can use melee abilities in the forms, however, so the Rogue maneuverability is open to you. Viable Shifter/X are probably limited to Shifter/Paladin, /Rogue and /Barbarian. I don't think your own spells work in the forms, like Firebrand and Taste for the Hunt, where your default weapons are replaced, if they are cast before the transformation that is.
I just realized I didn't want to go into specific class design, but ranted about it either way, lol. Anyway, they have a loooooooot of work to get this shit together, which probably won't happen for release.
