Mediocre.

[I feel like listing pointless inconsequential gripes with the game with a twist.]

Those things add up. I agree with you, regarding most of them. The other ones aren't worth mentioning.

[Fix Darth Malgus knockback mechanic]

We took him to lightning phase, positioned him near the abyss, used our knockbacks and he just went on to be vulnerable. Hence, he was slain.

Before we wiped three times, because knockbacks wouldn't work on him at all and just made him fall backwards, but not down the abyss.

Also, his own knockback tends to prison people midair where they either remain useless for the rest of the fight or die by using /stuck. This can be avoided by fighting him near the window though - guess it might have to do with the ability possibly being incomplete, so that you can't get back to the ground without a hindrance at your back.

["Addons are stupid and WoW is easy."]

I don't really miss addons such as gatherer or sth-o- meter, but I'd sure love to be able to customize my Interface according to my likings. Action Bars (as much of them as I want), Mini Map, etc. : freely moveable. That'd be good.
