One thing you should know about roles. When switching to units placed in editor on the fly in MP, it could mess up the role of the player. Could be bug, could be intended, but I would not recommend doing this. Create new unit dynamically if you need to switch to. Anyway, if role of the unit is messed up so is roleDescription.
Description

Syntax
roleDescription unit
Parameters:
unit: Object
Returns: String
Examples
Example 1
_playerRole = roleDescription player;
Problems
Does not work in single player.

Community notes
roleDescription works for playableUnits only. That means not on AI disabled in lobby and not in SP (even for player).
