I remember playing Warcraft III, back when it first came out...

Tyvolus4

only to learn a bit after its release that Blizzard (my fav game company at the time) was making a Warcraft MMO...I was like "oh wow, I am going to be able to roll a Dwarven Mountain King..."

boy was I wrong !  the cookie-cutter classes for Alliance and Horde were well thought out tho...
