New skills look pretty good to me. Ranged molten strike (volcanic fissure)? Yes please. Not to mention it's a slam skill so you can use the slam skill supports and such rather than the strike skill ones. The frozen statue thing looks weird, but might have potential. If you're letting all the cooldowns go off you're getting 170% weapon damage x6? Not sure if that's right though. Or if it won't just be awkward as hell.
Vaal Cleave? Looks broken, honestly. Headhunter effect with 20second duration? WAY bigger area with 20second duration? With the cast time increase and the souls limitation it looks like a decent playstyle too. Run around with regular cleave then when you spot some juicy rares you hit them with vaal cleave, gain their buffs and big area, then carry on the carnage. Plus, having played with it in the past, the alt quality cleave that grants LGOH is not bad at all. I mean, ya lol-melee-lol and all, but still.
The change to tribal fury is a good one IMO. It frees up points which is what you want since you're always hurting for nodes to spend points on as melee.
League mechanic looks decent, but I didn't mind the lake mechanic once they finally got the bugs worked out. I just got bored with the last league early and got distracted by other things.
Overall it looks like GGG did a decent job on the changes. Hopefully it's a bounceback league just in time for the holidays.
