My shammies are 42, enhancement specced. DW + Windfury = walking tornado. It's a sight to behold. And with totems, things are just sick. Cleared RFD at 40, which was about +5 to the trash and +3 to the bosses, and had no issues. Gonna try uldaman tonight at 42 and see how it goes. Casters are cheese with grounding totems and melee are almost cheese with 5x healing stream + str/agi/AF. :P
Ya it's basically the same thing with WW+WF+ Cleave/SS. Just oblierating stuff...

[edit]
My biggest thing I love about 'em: zero downtime. Sub-30 (i.e.: pre-windfury) they were sucking pretty hard. Couldn't kill 'em but they took forever to kill anything else. Nice being able to take down +6 stuff, though.

The few experiences I've had in PVP lately have been over in seconds. They'd die without me ever having to re-/follow the alts. /rofl
Exactly the same with me on the downtime thing. Even in instances I could chain-pull for quite a bit before having to stop and regen my shammy's mana real quick and then continue whooping ass. It was more or less the same for warriors pre 30s although cleave did help a bit.

[edit2]
Oh, and regarding /follow and mob positioning issues. With shammies being basically auto-attack plus Stormstrike every 10 seconds, positioning is not a big deal at all. So much so that I'd not worry about it. For rogues, this is different due to positional styles.
Even though I made quite a few comments about positioning, once you get the hang of it, it really isn't a big deal at all, you eventually don't really even think about it and just automatically react.
I mostly put the several charts in to help ease people concerns about positioning who hadn't tried multiple melee too much and to give a few tips to those who had.
Good idea about /follow bouncing between the leader and the healer...I like that.
Ty, and just a side note, if you run into an encounter where you want your tank to stay still you can simply make a 3rd /follow macro that makes it so only you dps runs to the healer instead of the tank as well. I'm not actually using a tank yet in this set-up so I haven't actually worked on that macro yet. Either way this helps to take the micromanagement out of running your melee all around.
Thanks for doing this experiment Tdog. I love seeing people trying things that are out of the norm, and I'm glad you took this project on. Not only is it doable, but you enjoy it! If you are done updating this thread, do you mind me PM'ing you occasionally to see how the project is coming along?
Sure, I still haven't figured everything out that there is to figure out melee multi-boxing but if you run into a snag feel free to drop me a PM and I'd be willing to share any advice or experiences I may have had.
