I played Eqithan while you played Nanorab, and I thought the character was absolutely fabulous. The roleplay cracked me up so many times. But... at the same time I heard a lot of animosity over irc and various other channels.
I played against Kaisse, as Gharahka, and you sort of rubbed me the wrong way for whatever reason. At the same time, quite a few players voiced praises.
Also Optomkiptum I liked really much. I played some tribunal back then, can't recall what.
I think the thing is exactly, that while really well roleplayed, there's some quality in your playstyle, that tends to annoy the opponent. It feels kind of like you are forcing roleplay on the guy who just lost, and it can be really annoying. This is something you might consider, if you so choose.
As a side note, it might be good for me to study my own play patterns. I am certainly not beyond criticism myself. You know, when you point a finger, there's always three pointing back at you, and all that.
