Just like mages and hunters, rogues are perfectly balanced, it's just that people suck , they don't know how classes work so they can't counter them.
There is no OP class, just spastic opponents lol. This is the new AJ discussion trend. Yes Nadagast needs to learn from a 1 time 2200 first time access poster rogue, that's it.
You can use Deadly Throw to land interrupts outside of Subterfuge. In non-carrier bgs you also can use Smoke Bomb as raid wide shield wall during grip/vortext/beam. I usually go in with Subterfuge and move out again.
If you get focussed all the time you can also use Shadowstep and step back to your team but C&D is usually better for ccing ,multiple healers.
Usually I try to get restealths constantly and use Deadly Throw to annoy on range. Also interested what rogues with higher rating than me do in RBGs.
2x melee zerg setups r rly position depending so i cant say much about that but feral/healer is quite doable just make sure u dispell most of the predator swiftness from feral .
Go on feral till he trinkets when he does make a hard swap to healer and so on with silence/stun on healer so feral wont be dispelled u can get sap of it any such so , u can go for feral too but i rly dont like how tanky they r sometimes but ofc if u can get him to smokebomb without trink might be clean kill also
Your simply getting nervous and thinking too much and you end up getting raped by people you owned before oh well its nothing new it happens if you really wanna reach a specific rating that you need to buy something new badly i dno if thats your case but this might be one of the reasons that you always fail to get 1.8k...
After losing 1-2 games in a row when your close on reaching the rating you need i suggest you stop playing your already pissed angry and you are raging for sure which makes you play even worse and you end up losing all the rating you gained before stop for 1 hour or something drink/eat and then continue getting pissed and angry will never help you in anyway inside arena.
Hope it helps a bit cause i have been throw your situation before in my life :).
By the way remember everytime you say "this is the last game for today" its gonna be a loss thats scientifically and mathematically proven.
on spriest/rogue tunnel the spriest to reduce their pressure. you should rape spriests quite fast.
on disc/rogue your druid has to los/go bear when hes burning and try drink as much as he can. you can stay on the priest, since they have no poison dispell they'll go oom faster then your druid. just have your druid not eat fears.
hunter/moonkin is nasty dmg. start off on the moonkin and SAVE your kidney for the starfall. just dmg the moonkin down as fast as you can, when he pops starfall you can kidney/vanish cheap it while keeping dmg up. you can blind hunter to force his trinket and have your druid cyclone him to reduce dmg in and let aimed shot fall off. you can also disarm him if hes close to you.
