I am too vain to do what Cynwise had suggested - mog your gear into the lower PvP gear so that people will underestimate you, think that you're weaker than you are. I like my black and red look with my felpuppy on a stick. However, I *could* see how that would work, if you are someone who recognises things by gear, but as I am someone who looks at health bars and actual numbers, that psychology doesn't work on me - I hardly even see the faces of my attackers, let alone their gear.
However, Aza does. Yesterday when we were PvPing with Arvash, Aza in mid game said "Wow, this guy is good!" He obviously wasn't referring to me - I'm not a guy. Anyway, it was Strand (SotA was the double honour BG last weekend) and we were on the defense side and it was a pretty good game - we were going to win it. As I was noobfiring a demolisher and Aza was running back towards me to the same demo (Arv never seemed to need much healing - and damn he defused those bombs faster than me) and as a shaman fell before our Hordish onslaught and a demolisher fell apart a few steps from him.
"That shaman," said Aza, "is really awesome."
"The one next to the demo?" I didn't get a good look. I just saw a body fall, couldn't tell what it was.
"Yeah, he's awesome, he has been reading Cynwise."
My ears pricked up. "Oh?"
"Did you see what he did? He transmogged his gear into the crafted PvP set, and Cynwise said to mog to a lower PvP gear that so people would write you off, and he did exactly that! I saw him on the beach and I totally ignored him and was focussing on the rogue. Then when I went to kill him he had a ton of health and I realised holy crap, he's in full cata gladiator AND season 11 elite too!"
That leads me into my not-so secret project that I was planning for me and Sev. Half done as a lark, and half as something to confuse our opponents, we had a transmog project planned. His is finished, mine is still missing one piece. I hope to bring you the details in a post soon!
