The restructuring in HotA still needs to be addressed. Relying on miracle scrolls with control spells in HL+U is no more likely than getting control magic in Pandora boxes (which is also quite rare). This is perhaps the most essential thing that is missing for a complete game experience!
The problem remains; I also noticed that it's not much easier to get transport units, and ideally, there should be some guarantees, as in WoTA - sooner or later, you'll get the desired creature. But here's the situation:
the developers believe that things like restructuring don't fit well with the game's concept. But they also don't rule out the possibility of having more control distribution points. So, if you have any interesting ideas, feel free to suggest them. Although, in my opinion, the WoTA feature of restructuring so that the opponent doesn't get it is pretty cool:D
I can suggest increasing the number of pyramids in the deserts and introducing similar objects on other respawn points, but with a limited set of spells - creature, teleport, fly, resurrect, implosion, armageddon.... Or even just spells for control.
Perhaps increasing the chance of getting a spell from the mages.
I heard somewhere that in HotA, each respawn point should have a scroll with a control spell, but in reality, this is not the case.
And another option that has probably been considered is not restructuring, but upgrading spells in the Guildhall. But then the concept of the tower is lost.
