Not to be a dick or anything but thinking that Focus polys and CSs are anything more than slightly above average gameplay is laughable. Perhaps if you were doing it on someone that even had the slightest notion of what fake casting is and more importantly the faking meta, it may be a little more to front about.
Also landing a few CSs or Polys on people and including such highlight clips in a montage makes me physically ill. The people who are decent will know how consistent you are, however the shitters will look up to you as a god regardless -- who do you really wish to "impress" and/or receive praise from?
Dont let a few recorded clips go to your head, highlights are nothing more than taking the cream of the crop of gameplay which may not have been entirely your doing (your highlight might be a better player's lowlight or off day where they aren't playing up to their regular personal standards).
Consistent Play > Random Infrequent Highlights
P.S. You were an above average mage (by Cata standards, which if you don't know means not all that to gloat about) in Cata if I remember correctly, nothing more. Please don't think getting invited into any guild holds much worth, as I can guarantee you wouldn't have been on any A team roster of merit, or even got to play in a decent competitive match. I don't mean to come across as rude, it just really irritates me when people think they are "all that" because of simple things that happen to most conscious players on a regular basis.
Again, soz.
