I don't post often but I do want to chime in here. PoE is a good, fun game for those wanting Diablo 2.5. (even has the same map!)
The skill tree is awesome though, with branches going in all kinds of directions. I've only played through the normal difficulty so far, with a Templar, but the character was surprisingly fun and unique. Tactics used included Ground Slam for hordes coming toward you, Fire(or flame) Shield so that when a horde did get to you, cast + drink heal, few seconds later when the monsters deplete the fire shield... KABOOOM! Everything around me dies.. sweet!
And my main attack caused the target to explode on death, hurting nearby enemies.
Messing around with the Scion (holy cow she has tons of skill paths) and a rogue dude that is creeping towards trap damage increases.
