1 - Warcraft 3 - Can't think of any. I don't mean that lightly; been trying to think of a serious flaw for about a decade now.
2 - Guild Wars 1 - Shitty balance. Example: why were paragons so useless at party support
3 - Pokemon Platinum - Goddammit add in some fucking random battles for experience. I want to level my Pokemon, why can't I fight in the Battle Frontier for experience instead of grinding the same fucking 5 NPCs? And Event Pokemon can eat a dick.
4 - Diablo 2 - Poorly supported (lying character page...), hilariously bad balance issues (good luck soloing Hell difficulty with a sorceress), pointless BS that cuts into the fun for no reason (ladder vs nonladder)...
5 - 7 (can't decide which is best) Pox Nora - Single player is repetitive.
Halo 3 - Forge needed NPCs available. And so many weapon imbalances...
Warlords Battlecry 2 - WHERE'S WLBC 4? *sob*
...uh, I mean, there are some glitches and the elves suck (either mass ancient wisps or lose, and if you play the game a lot this shit gets old).
In terms of problems, I'd say the list would go Diablo 2, Guild Wars, Pox Nora, Pokemon, Warlords Battlecry 2, Halo 3, Warcraft 3.
Edit: *Looks at the post above mine on Warcraft 3* Holy shit I was actually ninja'd on that?
