I went through the same thing on my way to getting my Warhorse, and it felt like FOREVER getting from 95 to 100... so much longer than getting even the 15 wins before it... and then I was able to enjoy the game more based on how my party was doing vs. if there were problems in the alliance.

While I'm not changing GC's and forfeiting all the PVP rank-based rewards, I do want to experience being in the different Grand Companies for a variety of reasons, so I have a character on Leviathan in Maelstrom I'm developing. Once I get that to 50 I'm sure I'll be PVP'ing some with him so I'll most likely find myself in your party or alliance at some time or other, albeit under a different name.
