When you make it to Inheritor then it doesn't matter anymore.  I am finding that it is difficult, now that I am an Inheritor, to play Halo Reach at all anymore.  Yes, it is a *****  to deal with the cap when you are trying to rank up, I dealt with it for just over one year but, it is not a good idea to get rid of it when you have so many players AFK.  Patience and endurance, that's what it takes, not getting rid of the cap.
