[Loth] Risen / Necromancy upgrade
Risen are a really bad unit. At the begining, with few options available, they are somewhat ok, but later in the game they are just in the way, despite of the undead general upgrades.
I suggest to add an upgrade to the risen, through research (advanced necromancy) that upgrade their usefulness and maybe give them guard or rush (increase movement for 1 turn) or something useful.
They should be at least on par with rats (without upgrades) since rats CAN be made much better either way.
