yup, i experience that rogues are very effective for 2 main things in arena; firstly to wait till the battle really starts and then take actions.
Also the target i aim for is not essentialy the focussed target, more so i try to occupy the healers of the opposition so they cant get a single heal of for about 10 seconds.
Killing resto shammies is really a time waste as we noticed in the previous matches. But stunlocking him while the rest of the team goes for the squishies seems the way it works best for us. Especially considering we don't have the easy mode MS warrior.
Though the 30/31 setup is really the only viable build to have enormous burst damage, a rogue shines in trying to control opponents to take'm out of the battle for a considering amount of time. Blinding, sapping a incomming rogue (human perception is a bitch ) stunlocking/vanish/repeat stunlock is really good to get a clothie down in no time.
Also i heard that in nagrand MC-ing a healer is devastating for the opposition because of no heals incomming for them
All depends on the setup we face and how their style of playing is. Which makes it so much more intresting vs scripted bosses which become boring after they get farm status
just a dump of my toughts for now
