I don't mind that much doing the horrible, horrible rep grinds to Glorified for Mathos, Icewatch and Dragonslayers as it's a tolerable price to pay for the best (and, in some cases, only real option) runes for those slots. But I'll be damned if I'm going to do it twice or more if I want to make an alt.

By all means, keep the other things like faction recipes, pets and the like BOP. But unless the reputation requirements are reduced to something more sensible, the runes should be BOA so you can transfer them to your alts.
