Dungeon fighter online was pretty great, it gets better the further you get.
You want to pick the show-off classes though, which tend to be magic based.
Played thru the whole game with a friend who picked a elementalist mage and I ran an Asura slayer (magic swordsman) and we could do just crazy shit,
(1. Make black hole to suck in enemies to dmg them (Mage)
(2. Use light magic to bind all enemies in place for a few seconds immediately after black hole ends (Asura)
(3. Call down a meteor and burst fire from the ground (Mage)
(4. Suspend all enemies in air around you and swirl orbs of death hitting enemies several times before exploding the orbs (Asura)
Highly recommend that game.
If you like DotA type games, I'd recommend
League of Legends.
It's free to play, and it has a cool system where you can lvl up as you play games, and get access to special passives and active abilities to use on any hero, and it's remarkably well balanced.
