I'd just like to point out that if you want to mix poison cloud troops with regular troops, you don't need poison res troops, you need poison /immune/ troops. Even poison res of 99 will do virtually nothing to prevent you getting crippled/killed/morale-tested-until-you-flee if you spend a few rounds fighting alongside a poison cloud unit.

Don't believe me? Try Ctis troops + poison slingers or bog beasts or poison cloud spells.
