How are the top teams currently dealing with the constant fears, snares, etc. that make it difficult to even get the instant casts off?

We had a pretty rough night tonight, but overall came out ahead. 1615 was our top but the teams are just getting too precise, too organized. Tremor totems arent' doing a damn thing and I'm getting feared all over the joint.

The biggest problem I'm having is shaman not facing the target (especially with all the cleave teams) and just generally not being able to nuke even if I picked a target. Most games are playing out like:

1. Frost DK runs in an CC"s entire team - I trinket
2. Warriors fear bombs, tremor totems don't help much and they're all split up, all facing the wrong way
3. Atempt to regroup, have the shaman are snared and have to crawl their way back to the main, by which time I get fear bombed by the priest, or the melee is spinning so fast I can't face them.
4. Pop a thunderstorm or two if I haven't already. Targets go every direction and by the time I can find a target and get all the shaman to face them, they're already on me again

I'm currently running a pretty well gear holy paladin, he can keep people alive for if needed, but I have to stop and heal myself at times. Most of the organized teams will start to CC him like crazy once they've rendered all my slaves useless.

I find that my only real chance to instant nuke is before they even engage, but often times I get flame shock and elemental mastery popped, shaman get fear bombed and split up, target is already obvious at that point and struggle to get 1 or 2 instant casts on them which are futile when the healers are already popping CDs.

We played a handful of 2100+ mmr tonight, and I expect that kind of teamwork from them, but we also lost some games to much lower rated teams with 3 or 4x pvp/pve geared melee who are smart enough to aoe cc just as much.

Looking for some tips, we really want to at least get 1700 this week, I know we have the gear and reaction time

i watched Negativ1337's videos, hoping for some ideas, but the teams he's faced in the video, we have no problem with. We grabbed 21 points from a high rated team whose strat was to just dps like crazy but not cc, and that won't work once the shaman have gear
