One of the Crazy Buffers in the Legion has suggested I post reactions from those we buff as well as what it was that drew my attention to them in the first place. I haven't been keeping records of reactions, but here's what I have from the last two:
Revish- attracted my attention by simply handing over some items that I was looking for on a multi.
reaction:Wow, tyvm! Included item: clockwork core (quantity 1) (I of course sent him a reply with 25 clockwork cores
Dasmaniandevil- I have seen him be extremely friendly to new players, and he actually just gave me a silver star with no request for payment, so I had to buff him.
reaction: there actually wasn't one sent to me...
My favorite so far (this one is from memory)
Doctor Mojo- He gave me the required fiendish skulls and claws to unlock leveling after 25th level on my rare hunting multi, allowing me to continue grinding for the rare I'm currently searching for. When I asked what I could give him, he said "Surprise me."
reaction: "Wow, that really was a surprise." Then he requested an add to the mailing list so he could randomly assist with the buffing!
