Now ehm, i play mage rogue at 2.1k in season 4 atm. And i would like to correct you:
PRIEST ENHASHAMAN - You're making this way more difficult than it is. You can completely spell lock (stun/silence) a shaman so he wont even get to use his shamanistic rage before he dies, all this while sheeping the priest, and if he trinkets do a blind (o rly). Thing is, this requires high damage, but if you both know how to play, this is so terribly easy facing. If you don't know how to play, and ur damage sucks just because it's a shaman, you shouldn't be playing mage rogue at all.
PRIEST(DISCI) LOCK(HARD+)
This is not hard at all, since nuking the pet down is gonna happen in a very few seconds, and from there you can't simply let him summon again. You've got cs, kick, gouge, stuns, vanish-garrote, vanish-newstun to prevent this. If you haven't got the reflexes, i strongly recomend you start playing some games just to improve your reflexes. 0.5 seconds is easily doable. From there, i agree with your tactics, but i just disagree it's hard.
DRUID(RESTO) ROGUE(HARD)
This is not hard. As you say, cheap shot rogue when he goes for mage, but don't kidney shot. mage should just start loading shatter combo, as soon as rogue pops on him, because your rogue will stun him before the enemy rogue even gets to kick. Since you don't kidney shotted, just do a Slice and dice, for more damage for the next seconds of the match. Druid will pop out cos of shatter combo on rogue, so rogue sprints and blinds him, he's by then forced to use trinket, and that's where you go for him, cheap shot, gouge (mage loads shatter if the rogue is sheeped, if not just pet nova - lance), then kidney shot. When he goes low, vanish-garrote, after that place the counterspell. By then he should be dead. This requires alot of your mages survivability, but it aint really that hard.
I play rogue in this setup

. My tactics relies on your players being good, but hey - you're not born with it, it's fully trainable. So gogo practice.
