Guild Wars:

 

Pros:

Great graphics.

 

Cons:

Constantly being countered by the programmers to make you fail.

 

Patches:

I've stated this before, but it still applies, especially with Guild Wars.  They constantly patch to counter everything you do, making the game more difficult.

 

Unbalanced:

Unbalanced in more ways than 101.  Don't even want to talk about it.  Terrible.
