This has been bothering me a lot lately since I've been doing dailies on isle of thunder and the amount of times I met players of opposing faction, nearly killed them and then had them slip away because of some bullshit mechanic is really annoying.
The worst offender is rogue with tard-friendly vanishes, cloak of shadows, blind -> restealth and spammable burst of speed making them slippery as hell. I understand some impish appeal of the class is slipping in and out of combat but this is ridiculous.
Next on the list is mage. Iceblock -> greater invisibility. Why is that a thing -.- And even if not, pom -> poly -> run away.
Third offenders are hunters who can web -> trap -> cc you for eternity while they run with their own ten dozen sprints and pet stuns. Bonus points for deterrence -> black hole (engineering thing w/e it's called).
Druids aren't on the list. They are above, beyond and between the numbers as they are the zen of annoying escapism. Between blink and 50+% health heal (neither of which you can silence) they also got root / cyclone / solar beam / ursol's vortex / dash / practical immunity to slows in addition to being able to be a healer AND a dps at the same time. Were they mental when they designed it?
Really, most if not all classes have some bullsh*t way to just reset combat and run away like little chicken sh*ts that they are. I hate it and I hope Blizzard really take a look at it in WoD in addition to the amount of cc. I really hope they do something cause I'd really hate for Ashran to be an annoying chickenfest.
