So, while the embermage does take a while to get going, once you onlock burning pillar the game becomes really fun. The cooldowns are small enough and with increased charge rates you can really spam your spells. Closest feeling you get to D2's sorc and no comparison to D3 (which feels similar to embermage below 20, way too much melee for my taste).
Love socketables, especially transmution
They also did gems right, with level requirements both for transmuting and equipping them
Absolutey love loot as quest rewards, being able to choose and seeing them before accepting a quest
I finally get to add sockets to items (yeah, wtf D3)
Gambling rocks
Considering the graphics, it runs absolutely amazing on my laptop (HD3000, D3 is near unplayable)
Oh and So refreshing being able to play a game without these constant, forced interruption that serve absolutely no purpose. Fuck the TP delay in D3, fuck ID delay, fuck end of dungeon portal delays. Fuck the cheesy, shitty cutscene interruption. Fuck the boss and fairy chat spam. Fuck the linear, mandatory and forced quests. Fuck the quest "rewards" (lol here's 500 gold, go buy some potions).

Imo, TL2 with battle.net would be a worthy successor to D2. But even without it, it blows D3 away when it comes to gameplay, loot and item customization.
