End game diversity mod

Maybe treants can be used in lategame as tough N bf casters. Especially with E they have access to Gaia Blessing, and Mass regen+Relief are both important for big armies with several SCs, while equipping N boosters on lowhp n2 human mages (national or indy) seems rather risky (taking into account various remotes cast onto such armies and consequences of losing the buffer before the battle). Usually I used N tarts for that role but they are unpredictable and stopping the whole army due to craziness of one key caster makes me sad.
