My DK partner in 3's has better uptime on Frost Mages than I do even without our healer spamming dispels on him. I don't think you realize how Ret plays in arena right now.
Also, lol @ the Divine Shield comment. Because I'm totally going to use a 5-minute CD for 8 seconds of half-damage on-target time. As for Freedom, I'm lucky to have active for even half its duration.
Don't read too much into my pun, living in a bubble was my not so clever way of telling you that not everyone gets to have your mobility against frost mages.
And of course a DK would, Deathgrip, AMS, Icebound Fort(this breaks deep freeze right?)
Yet MY class was nerfed due to having too much uptime and being "annoying" see the double-standard there?
You can't really count Death Grip, as that also affects my on-target time.
Anyway, my mobility has the potential to be good on Frost Mages, but I can only Cleanse spam so much in between Judgements. It's even worse if I don't want to Judge on CD to benefit my speed boost as much as possible.
Feral has higher pressure than Ret does outside of CDs. Ret's burst is very cooldown-reliant, whereas Ferals can put out strong pressure without the use of their DPS cooldowns. You lost mobility because of how high your pressure was, and your damage was overall buffed further to boot. You must also consider that your utility toolkit is more offensive-oriented than mine, which makes you that much stronger on teams (especially considering how strong dispels are against my utility).
