Crosstraining is dangerous.

I think if it were to be done at all.. it would have to be something like 1% in a crossclass skill per overall level or something like that or trade that in every 10 levels for *1 of a crossclass spell (but never higher than say *2).

Even then it opens up the possibility of some combinations being much more broken than others. For example AMs and SMs could train iron will, but an elementalist wouldn't be able to train spells in any other guilds due to not sharing any casting skills.

It would be very tricky to say the least.

It might be kindof neat if people could train others in their clan for an obscene cost. Say you could teach 1% of a skill for each 20% of a skill that you had and it cost the recipient 5x the normal dev cost.

Even that though would benefit some more than others so it would still be really hard to do.

Actually the more I think about it, the worst it seems.

Might be better if you wanted to do crosstraining if you just let people pick 2 guilds, average the devs they would get for each and let them train both. A fighter elementalist might be interesting.
