I've done all content rather easily and on budget builds.
My shaper runs are usually one or two deaths as defenses are the last thing I work for if at all.
High end bosses are more a dps fight than anything anyway as dodging most skills are rather easy with whirling blades, except for chimera hes a fucking fuck.
All breachlords are easy in comparison to guardians just truck in and out dps bosses they have shit hps and clearing breaches is the same as in maps only with an omg wat do time limit.
Content in path of exile is meh. Right when it comes out its like "Oh wow this looks interesting." but after actually playing it and realizing that its not, we go back to farming the areas that actually give us the best returns. 3.0 wont be much different I think. Or maybe it will who knows.
Also average jsp user is better at the game than average user anywhere else. It's been that way for most any other game jsp has a forum on also, wonder why that is?
