great video, room for improvement but thats the way it is. if i may be so bold as to give a few suggestions:
-toggle "hide mousecursor while recording", it gives for some confusing moments where i'm looking at you changing gearsets and clicking new targets rather than watching you play, just an aesthetic prefference if i may.
-try with some focus macros! these are some of the ones i use:
/focus [Target=Mouseover]
^ sets a focus target on whatever target you have mouseover, letting you spam frostbolt while you set focus on the healer
/clearfocus
^clears focus when moving from one fight to the next that doesn't necessarily involve that player.
/#showtooltip/stopcasting
/cast [modifier:shift, target=focus] SPELL; SPELL
^ i use this for: Polymorph, counterspell, bandages (if you're playing D, it can sometimes be a good idea to keep your fc on focus and use this focus bandaid macro.), it is relevant and vital, being adept at swapping targets only gets you so far :j WARNING: many players prefer to keep these on two seperate buttons which would look like this:
#Showtooltip
/Stopcasting
/Cast [Spell]
-
#Showtooltip
/Stopcasting
/cast [Target=Focus] [Spell]
^ this version with two seperate versions frees up more space for individual binds, without taking up modifier space. (say you have x key bound to shift+4, it doesn't work to have a spell with a shift modifier bound on the regular 4 key then).
i prefer the first version.
playstyle-wise,
-remember to double-poly (start casting the 2'nd polymorph right after the first), this way, any resisted polymorph is still gonna go through, obviously you stop casting if the first isn't resisted! =)
-you seem to be adept at handling rogues, i like how you anticipate the trinket on the pet nova and immediatly novas a second time, however be careful with not just throwing CC at people, use it wisely.
-for the love of god get engineering, herbalism and engineering are the two best proffessions, i cannot stress enough how relevant it is to get a polymorph off without fear of focus Shs etc.

you're a really good mage and it was a good watch! keep up the good work man, i hope you'd want to send in some footage to That 19's Show, we could use some mage footage! =)
