Just my few flaws with the rank system..
1. It does not in anyway inspire citadel participation.
2. It favours higher* lvls with the increased xp rates (*different in different skills)
3. I don't see how xp is valuable/beneficial to the clan and therefore representative of rank in the clan. The only benefit we get is higher clan ranking. This does not improve the clan's game experience, except possibly attract idiots looking to be in a high ranked clan. It does not help individuals lvl their skills (except rushing to get more xp for rank) or make the clan fun and enjoyable, which I'm sure we all want.
I understand it can be an indicator of time spent with the clan, but it is a very poor indicator indeed.
All and all, xp does NOT show clan participation, and as such should not be used to rank alone.
Yours sincerely,
Me
(I reserve the right to add more this)
PS I also which to stress the fact that I don't care about what rank I am, but I do not want my clan in the hands of people who can just skill fast...
