I don't think skill training needs to be changed.
Yes the multi class feat is better...as long as you meet the prereqs. In this case your warlord was able to. If he was a charisma warlord and wanted arcana, then he would probably have to take skill training.
Further, the multi classing feat can only be used the first time. Then you have to start using skill training to get other skills. So I think the feat is fine as is.
