I had my first run in with a negative comment yesterday. Up till that point most folks had just been curious or given a few /wave or lols.
This fella randomly whispers one of my Shaman with a "CHATER" (soon corrected to cheater).
When I asked why I was a cheater, he responded that I was using a Multibox to control 3 shaman rather than 1.
I replied that it wasn't cheating, and he should look on the forums and his ToS to see that it wasn't.
That got a 'Whateva' back and the expected 'Gunna report you'.

I was soon his ignore list (don't you just hate that when someone starts abusing you, then switches that on when they know they've lost?), however I guess he didn't realise that my Pala was leading them, as that was never mentioned nor whispered.

That however has given me more confidence to run round as a group in cities. Till then I'd either stuck to Exodar or split the peeps up when in SW/IF. However I left the ladies parked in the Shammy trainer in IF last night in formation, and that drew lots of giggles from the other Shammies visiting
