Just found out about this new F2P game that looks alot like Diablo 2, with some upgraded features.

There will be 6 classes on release, only 5 shown so far. They have this gem system that will work like the runes in D3, where you can adjust skills to have bonuses like piercing, inc splash damage, inc radius, multiple projectiles ect. They also have a different skill system that lets you specialize in certain abilities while still getting some general buffs in other parts of the class. They also do something unique with potions, you collect the potion containers and they regen hp or mana as you kill enemies, with bonuses on containers like "refills to full on crit"....this means when there are alot of enemies you regen your pots faster, but on a boss (that doesn't have adds) you have limited potion use.
Check out some of the "lets play" vids on youtube it looks pretty good. People will probably cry about the graphics but not a big deal if you were a fan of D2 and looking for an updated version instead of a new spin on the game.
