At the moment, given training for horse takes 180 days, I'm training all my toons in riding.
However, this is a strong disincentive to me to ever delete any of them and to try out new and different builds.
This seems a little counter to the stickiness lure that you get from investing that time in the horse training in the first place.
I can't see a good alternative that would still accomplish the same ends, though.
Hmm. Having the training be permanent per character slot might work...
