You can easily find greens that add lots of +1 to 2-3 different attributes. I was able to equip my hybrid Battlemage type with full yellows and max essence stacks with a bitching 2H Scythe.
Was able to get 20 STR, 15 Dex, 20 Int, 14 Con, 17 Speed, 18 Perception. Weapon Damage Unbuffed was 989max, with buff to 1,987 max, with 49% crit Chance, over 100% Resist in all Categories, but Tenebruim was was at 50%
My Ranger, Utility Character only had half Yellows, but was able to get only about 8 Str, but 22 Dex, with 18 Speed, and 18 Perception.
I found that a lot of my End game gear had that +1 Perception or +1 Con and i usually choose Perception since i was able to get so much resist I just healed on everything.
Pots were useful in some fights though when something just walked up to you and slapped you hard, or weakness you. But overall easy.
I just want to be able to do some stuff with my Characters I finished the game with, but you can't so... gotta wait I guess.
