Generals are less fun than assassins . Should control portal reinforcements
Even if generals are tweaked to be as essential for a team as assassins ( which they are not, currently ) They will not be as fun. Call me weird, but adding health and mana and shortening cooldown to my allies is just not as satisfying as fireballing a retreating red-health demigod.
And what kind of a general stands beside a portal and just watches a reinforcement wave happily heading for the nearest enemy tower to get slaughtered ?
Powerful auras for generals is one way I suggested to balance generals, allowing them to seriously enhance minions ( all minions, not just idols; and seriously = NOT +50 health ) but is still passive. Control over reinforcements can be a natural way to make them busy. I mean, Rook can think of stun+warp+hammer, other assassins have other combos. General have less to be active about in a battle ( QoT is okay, the rest are not ).
If generals could, for example, order catapultasauri to shell a tower position, with soldiers waiting behind to charge a demigod, and a powerful mana-consuming aura to activate and make them a force to actually threaten the demigod - that could be nice.
Watching your expensive idols feed another demigod's gold and xp with a couple Fire Nova / timely-thrown Mines is not nice.
