Very nicely done, and agree with pretty much everything in there - I think a lot of new gladiators are relying far too heavily on flash and not realising the fact that most of their threat comes from Rage of Halone. You might want to put in a line about the relative threat (from the spreadsheets it seems Rage of Halone does roughly THREE TIMES the threat of Flash and Savage Blade, which are about equal with Blade ahead a bit).

Also, you could perhaps mention Shield Swipe. I see too many gladiators macroing this and spamming it, thinking it's good threat. It's worth mentioning that it's use is purely for solo dps and damage reduction from the pacification, but is a very low threat attack.
