Hero Selection VS Unit Selection - Brains Help Me Out

Its pretty simple...

When i select for EG: 4 footman, I can activate Defend with a single click because all units fall under a common group. This is not the case with hero's. I am developing a map where all units level up, so therefore they have to be based on Hero's and changed to suite the units in Frozen Throne. Is there a way to be able to select hero's like units (Commonly Grouped when pressing TAB) and have their skills work in the same way?

Any suggestions or work-arounds would be MUCH appreciated! Also if you know of any simular maps, please post them here! ;)

Another thing, when you make a hero ability a unit ability it can only be cast by 1 person even though it should be cast by all units. I would appreciate an answer to this question too as I had to do some triggers to emulate it, but they aren't as good as just being able to do it.

Great, Ive had a few maps like this in development in the past, im very interested in seeing how it turns out. But with your question I dont think theres a real way of doing it, besides giving most units passives/auto casts to limit micro.

I think that's impossible...
the unit groups you are talking about are groups of the same kind of unit, regardless if they have similar spells or not. I don't think there's a simple way to do this, unless you want to do a lot of triggerwork.
Basically, you make a dummy unit for each of the different units you want to have that can level. Then you make one hero that looks like all of these units (footman for example) and has no skills whatsoever. Then by use of replace unit and add skill triggers, you can make it so when you buy the dummy unit, it is replaced with the blank hero, and i is then given whatever skills you want. Then when you select a bunch of them they will all be categorized together (as if they were regular footmen) and when you click an ability, all of the units in the group with that ability should use it (unless it requires a specific target such as heal or blink requires). Sounds complex, I know, but that's the simplest solution I can come up with. Also, make sure that if you want your main hero to be able to cast with the footmen, he'll have to be the same dummy hero as the rest of them or else he'll be selected separately like normal.. Did you get all that?

Ye im with you on that last post - Thanks
