Well, no-ones bashed it yet so I feel it's my duty to step in.
I really couldn't have cared less about the bugs, i mean it's massive and does a lot of new things of course there will be bugs. Anyway most of the time it played fine, performance wasn't too bad either.
However the game was fundamentally flawed, and thus just plain bad.
The combat system
Firstly the combat system while at first seeming active, is actually less active than warhammer or wow! As while you are doing a combo you cannot move, this means people just stand next to each other mashing the buttons. I.E there is no skill involved in the placement of your character, like there is in other MMO's.
Alongside this nearly all the skills have long cooldowns 3s ish, while wow and warhammer have many instant attacks, what this means is there is no room for skill because lets face it my gran could plan out the correct moves and time them correctly if you only had to press them every 3 seconds! Instant attacks allow for people with quick reactions, and ability to quickly cope with different situations to excel.
Motivation
Due to several reasons, firstly the lack of fun quests, lack of decent rewards and no promise of a decent end game to look forward to.
You start of playing, and it's kinda fun figuring out all the new stuff, then about half way it hits you - the game is so linear there is so little to do out side of the PvP mini games and terrible dungeons that it seems pointless. There is no reward for playing.
Misselaneous
All the characters look the same, so don't even think about "character development". Crafting is terribad. The community is rubbish, no feeling of the need to group together. End game sieging is a lag fest of pure boredem. The story sucks.
I could go on, but at the end of the day this game is bad. It's ridiculously bad. None of my issues have yet been fully adressed, just do yourself a favour stick to the books, masterbate over a picture of arnie dressed as conan if you need to. After that go play Kotor, then the witcher , then fallout 3, then if you still want an MMO go try WOW or Warhammer online.
