Good games must be hard. D3 was hard at start and it was good.
Not any more though. Monster damage was nerfed by 100-200%, monster HP was nerfed by 200-300%. Elite packs were nerfed to the ground - bad suffixes were removed, annoying suffix combinations were removed, elite packs don't reset their HP when you run away from them, elite packs don't enrage any more when you fight them too long.
If they managed to beat the game almost naked after just few days of farming and you can't do this after all these nerfs, with 20-50x increased item drop AND with the implementation of absolutely insane crafted items, there is something wrong with you, not with the game.
