Zero margin for error past 2000.

Beat a 2300+ team 4 times in a row, they figure out a strat we can't counter - never beat them again. Have to quit for the night if that's the only team playing.

Wizard cleave? If we get a few wins on them, they adjust to this exact strategy:

1.
- Get grounding totems down.
- Totems on cooldown? Bloodlust + shadowfury + global any of my shaman, through pain suppression.. 3 shaman left, can't kill anyone with gear.

2.
- Get grounding totems down
- Realize I have them ready, not on cooldown - LoS game and oom my priest, or even attempt to global my lead shaman while I can't really dps anything because they'll just see me cast and run away.

God forbid we get them on blade's edge or dalaran sewers. Ele shaman flanks, or even just runs straight at you, thunderstorms your guys to the far corners of the map. We started having my priest pop the grounding totem and I hit IWIN button as the shaman rides in... but most of the time I leave the shaman at like 5% hp as I can't finish the macro (CL would have killed them) since I'm in mid air at that point.

Blood elves on the team? How about shadowfury + aoe silence. Trinket + drop groundings instantly won't work against that.

I have over 3k spell power unbuffed on my main, and a lot more with totems and cooldowns, and rocket gloves, and a single cc'd shaman, or a little rng, and your focus target, whom they have no idea you were targeting, lives with 1000 hp and gets a NS heal to full. After that, it's difficult to coordinate any burst that's really a threat to a good LoS team. I'm still just at a loss for words as to how people manage to run 10 yards behind a pillar during a bloodlusted lava burst cast, and avoid them all. When I play solo I can't even make it 2 feet, I just get hit behind the pillar.

Massive amounts of passive healing that with a little RNG will save your nuke target with just enough HP to get a nice big instant heal.

A plethora of AOE cc that gimps a grouped caster team to no end.

A bubble on practically every class that any player over 1500 rating has wired to their brain for instant reaction time.

List goes on. But I'm sure we'll get a little lucky streat and hit the 2100s if not 2200, but I still don't have a good proven strat to get there. We're already using every trick in the book, all kinds of split cc with arena1-5 targets, interrupts, focus, hard switches, thunderstorm rotations.. what's left?
