I put points into DEX to get the minimum needed to use level 30 equipment, points into INT to get the minimum needed for +1 Mana Regen, and then dumped the rest into STR for more Health and Health Regen (I was expecting STR to have more an effect on damage with the latest changes but that's not the case).

All my equipment is DEX based:

Jeweled Thief's Thin Dagger (pink)
Wing Shield of Legends (pink)
Assassin's Frosty Leathers (green)
Burglar's Penguin Snowcap (yellow)

With the latest Warrior and weapon tweaks, I think the best build is with more typical warrior weapons and a STR build, but I expect weapon speeds to be tweaked some more. Doesn't make sense to have crossbows, swords, scimitars, 2-h swords, all faster than daggers.
