Yeah IMO the loot system in TQ is great, Monsters using the items they drop and MIs, all A-RPG should learn from it. It never made sense to me that a group of flies can drop an armor.
And gold too. Vultures and whatnot can swallow gold, at least.
TQ >>> D3, IMO. I bought D3 to have some comparison between it and TQ. In the end D3 only managed to hold my interest for couple of hours, though I do play it every now and then for a while (after all, I paid good money for it so I have to get something out of it). Completed normal with a barbarian, but did not like it. The only things I prefer in D3 are randomized levels (some more variation in levels) and widely destructible environment. TQ, OTOH has more customisability (character skins, playable monsters, entire game mods) and somehow just feels better.
Never make fun of dragons. You will just make an ash of yourself.
