Sorcerer lords should rush magic then blue line, and have a variety of chorf units to make up your higher-end armies.
Overseers should rush hobgob redline skills and the unique hobgob buffs for efficiently shitstacking gobbos.
Heroes depends on which type of army you stick them in but you do want to stick them in armies since they aren't subject to the same unit caps your units are and they're all good.
