I had a fun nightblade hybrid build for dungeons, it was great when I used siphoning attacks, I had to occasionally hit something with a light attack and all was good. But according to the patch notes and what I saw on the forums siphoning attacks will be nerfed to the extreme, and now only returns a small amount of one resource. There's no longer a 10% chance of returning a resource for each hit either. This is very bad news for all melee type builds, even the hybrid I liked.

Weaving light/heavy attacks shouldn't be an issue when fighting a boss, but it's going to be a huge pain in the butt to connect when chasing down crowds of trash mobs in PVE/ players in PVP. 70% of the time I'll be facing the wrong way for my aoe skills to effectively connect as I attempt to chase down and hit some trash mob schmuck with a heavy attack up close. Even pure stamina melee builds already have crappy AOE dps, this requirement to weave heavy attacks will hurt melee dungeon players even more.

Ranged users could easily pull it off, sipping tea while left mouse clicking at things from a distance. If all the changes move forward as is I'll be ranged with a staff, same as everyone else, using siphoning attacks and elemental drain. If resource regen is as bad as I'm thinking it'll be, I might play around with a bow /caltrops too as a stamina drain. Heavy attack damage relies entirely on weapon/spell damage, not on the max amount of a stamina/magicka, so I'd go with Pelinals, ranged weapons, split magic/stamina CP and very high weapon/spell damage stats, not sure about the rest.
