I need to keep working on my RAF teams...

I got the gnomelox (Glox) to 60, the gnomages(Gmag) to 60, the
draneishams(Drsham) to 49, and the undeadrogues (UDR) to 62. I also
have the upandcoming taurendruids (OOmkins). But....MAN!!! these UDR
are FUN! (granted these are at lvl 62, and I havent had much experience
attacking much higher lvl targets. Insert grain of salt here)

I'm
specced for subtlety on all of them, and shadowstep is the order of the
day. With Honor among thieves (even with only 12% crit atm), 5 combo
points are almost ALWAYS on the target. Im even considering removing
Hemo from my guys, and I not using a special attack (sinister strike,
Hemo) at all??!! I still haven't even used premed yet.

My strategy:
Everyone shadowsteps.
1 char does Cheapshot for the stun, and cause most casters will wait for the kidneyshot to trinket.
1 char does Garrote for the bleed on rogues/druids, the 3sec silence for mages and other (smart)casters that trinket.
3 chars Ambush for damage. With the new Waylay talent (70% speed reduction on ambush crit), I don't even need the crip poison.

Then
the finishing moves, I have 4 separate macros. Low health means ill try
to finish them off without a kidney shot. Eviscerate, rupture, and
kidney shot are used a lot, and another macro will dismantle if i think
i can handle the melee target after the stuns all wear off.
5x stacks of deadly poison also work wonders on targets.

Spec at 80, I'm looking at:

Yes,
yes I know, all you rogues out there... ZOMG Hemo daggerz??? But look
at that spec, 5% crit in Assasination, 50% offhand damage and another
5% crit in combat. Another 50% crit strike chance for ambush in
subtlety.
I could also drop the blood spatter to go shadow dance if it looks like 3x ambush x5 chars is necessary lol.

Anyway, feel free to rip up the spec or whatever. We all learn from other's input.

Multiboxers need to think differently, You can't spec like a regular PvP'er and expect to get full advantage, so I think you are on a good track. I ntoice that you don't have the +30% backstab critchance tho, wouldn't that be awesome?

I feel kinda guilty heh i haven't even trained backstab.
I guess I should at least talk about the bad parts, cause they do happen, and sometimes more often than I'd like.
My rotation is opener, hemo, finisher nearly always. Sometimes I dont get any opener or finisher so its just hemo till dead.
When shadowstepping with all 5 chars, server lag tends to make it work out right where the main will go first and the mob will do an insta-face to the main and the four other chars will end up behind the target. this results in 1x cheapshot and a quarter second later the amushes/ garrote come. Regardless, the cheapshot almost always happens, so it isnt always a huge problem. When it happens perfectly, the ambushes crit and its instadeath for the target (15% of the time. Expect to see more often as crit goes up).
Problems with 5x shadowstep:
Sometimes all chars end up on same side of the target resulting in no ambushes or garrote, just regular melee.
Sometimes when this happens (due to a /follow in my macro cause of melee hits stopping the follow) the main faces the target, but the 4 others then /face the main without doing any more damage. I counter this by walking through the target on the main to help keep the alts facing the target. sometimes its not possible tho due to the target being against a wall.

Never considered boxing rogues, sounds fun. How has it been leveling with positioning and all? I'm leveling four druids atm but I'm caster only. Maybe at one point I'll give cat form a shot, after I get mangle.
