SmogBranded: so are you saying that both the commander/warrior heroes are useless?
Warrior/commander at level 20 gets reincarnation. His health pool becomes bigger than one of the Hydra. This is really strong choice.
commander/warrior at level 20 gets +1 teamwide health regen during battle. Yes, this is somewhat useful on gargoyles, golems, mechanisms and undead:
golems - hard to replenish quantity. Minotaurs in T3 better than golems - faster, round attack, berserk.
gargoyles - Nothing spectacular on their own. Harpy, at least, can get agility.
Mechanisms - slow you down, +4 to ranged attack from Strategist much better for them + Scout's skill for Strategist gives teamwide mobility too. You can't resurrect them. Basically, horse archer is much better choice for ranged damage.
undead - regen would kick in on ghosts only. T 1, 2 units can easily die and you can't restore them without contacting your wizard.
Other choices for commander:
Strategist - WAAAGH aura, fresh units have more dakka than seasoned veterans in other armies. Best initiative in the game. Amazing mobility and pathfinding. His bonuses work on own bow/crossbow. Third strongest archer in the game.
Commander/mage - T3 and T4 spells. He gets more exp than any other commander multiclass (leadership+wisdom), have more spells than other commanders, and some combinations are really-really game changing. Teleport and hydra/spider, stop time (mass astral energy), resurrection (
can save veterans), dragon form (really easy to make veterans from something squishy, like slingers), to name a few.
Like TV AD, "look at ^, now look at +1 regen"
