Thanks again, are you calling me a WoW noob though!
WoW wasn't my first mmo, AO was :P
In all seriousness, i haven't found it that harder especially those things you can easily duty queue for what i think are on the same level of LFR.
Obviously scaled content will be different, as for holding aggro it is rather easy if i don't forget to turn on my tank stance something that is a bit of annoying mechanic i am glad they removed in WoW a while ago.
