Well to start, there is probably a lot more story and lore to Warcraft than you would realise, it's just done in a different way to most games in WoW (shown in quest descriptions, in dungeons etc), if you had played Warcraft 1,2 or 3 you would see a lot of the story done in a more linear way.
The graphics are a bit outdated for a four year old game, but the art is fantastic, every zone looks unique, and to be fair there have been graphical updated in each expansion (better shadows, better particle effects etc).
The only bugs I've found in WoW is armour clipping (rarely, and usually gets sorted out) and getting stuck somewhere (between rocks for example) and not being able to move, which is sorted by pressing the character stuck button, so not much of a big deal really.
It's worth at least playing the trial and seeing if you like it (worth trying even if you dont plan at all on getting it because of monthly fees too :P).
