One shaman doing NS/CL doesnt mean much, 5 different people doing NS/CL is better
I never insinuated otherwise. But several arguers are claiming that the normal elemental population is so low that multiboxers are the ones the developers are nerfing/designing around. I simply pointed out a small case where elemental shaman solo-boxers were prevalent. Because of their burst, they made for better PvPers than raiders, though that's not saying much since survivability of soloboxing shamans in general is relatively poor.

I didn't just roll multiboxed shaman because I saw others doing it (at the time, everyone was locks anyway). I rolled 4 shamans because my main (the 5th) was already 70, and rolled a tank (paladin) to go with them. I never specced enhancement until bt/hyjal/sunwell, and leveled elemental and raided Kara-SSC/TK resto. So I would say my first perspective of shaman would be that of a solo-boxer. Prior to multiboxing, I was Dualist in S1 and quit PvPing to focus on leveling after. My primary perspective, however, was raiding -- and I won't claim to know much about arena'ing anyway since I haven't really kept up with it or made it any sort of primary focus.

I'm horrible with composition names, but several comps included an elemental shaman to just blow their quick burst, throw heroism and as many offensive purges/earthshocks as they can, and then drop dead since they have little survivability. Of course, this was likely because enhancement completely failed at PvP, so elemental was more desirable due to ranged burst.
