Well, I would like to start off if you're going to do an aim based combat system then the selection of a target to hit them needs to go bye bye.
The thing about what makes M&B combat work well is how the system is built to be a bit slower overall. This makes the melee combat system work very well with the ability to block and attck in different directions.
Since it is slowed down just enough for you to enjoy the fight and able to watch for incoming hits so you can block them and then counter attack.

When you go into combat mode nothing changes except you have a reticle. The movement between you and your target seems clunky and spamming all at the same time.
It needs to have that dodge and counter attack direction feeling.
Not sure if I am even explaining it correctly.
But as you can tell I agree with JCatano the M&B type of combat would be awesome for this game.
No one has tried in a MMORPG game. I have heard it can't been done.. Why, I have no real clue. Maybe someone else can explain why or dismiss it.
