Better hotkeys is a fact and valuable point though if the speed is not taken into account having better hotkeys has no effect on the game play.
Hotkeys are a way to make something faster so their effect really is tied up to the speed the game is played at.
Because we all agree here that the overall effect of speed is being detrimental for humans I guess we can safely say hotkeys are a non factor regarding human vs orcs balance compared to ease of actually using spells if anything it makes humans suck just a little bit less but they still suck.
What would make lust not effective the lower the speed goes? It still would last the same amount of ticks and can still be always up and math show its effect on hit points per mana spent is still better than heal even if ogres only land 1 punch.
Ogres and Paladins regenerate mana at the same rate and have the same maximum mana.
Which makes comparing their potential effect on hit points more relevant to analyse their efficiency.
As a matter of fact I am willing to bet the slower the game goes the better orcs tend to utilize their lust time.
But yeah that effect is more visible for heal since the spell is that much harder to use.
My point being even if both players use perfectly their spells Lust still has a better mana vs hit points final effect ratio.
Holy vision is a great spell but is not that much better than eyes of kilrog. Especially when speed is removed of the equation the eye of kilrog will allow you to check pretty much every mine / potential expo of your enemy without spending that much mana humans will have to spend more than one holy vision to get that same information.
So the way I see it although holy vision will allow you to prepare an engagement better in some situation it is still not that great in other situations that for me makes these spells pretty balanced.
Also there is the fun factor of eye of kilrog allowing you to make packed enemy destroyers sink each others
Every single number that differ and is not relative to game speed goes in favor of orcs being the trump card race.
All I am saying here the imbalance is a thing and facts are there to back it up.
Now it does not mean it is a problem that has to be addressed but facts are facts.
