Anti Map Hack system for revealed maps

So, i want to make an AMHS for a map that is already revealed, such as a Enfo's ETS.

The problem is, usual AMHS wont really work because you can see all the units, except a few invisible ones. I just want it to prevent people from watching ability cooldowns and such, which would be a BIG advantage.

I could ofcourse just resort to the the spam of un-renderable stuff which crashes the map, but id rather use a different method.

any ideas?

EDIT: C'mon guys, no JASS wizardry?

Make part of map ALWAYS invisible, but just not put it in camera bounds, so it seems as whole map is visible.

As far as I know, Enfos requires vision over the other half so you can use their extension spells and stuff to fuck over the opposition.

yup, in Enfos you can see the whole map at all times, and there is a spell that can target anywhere on the map that reveals invisible units.

So u guys just suggest I go with the loads of sfx to make the others lag out?

there is no need of AMH on maps with out fog of war.

yes there is, as i said before, if you can watch the cooldown of your enemies skills then you have a big advantage, as you can offense them.

MH allows you to watch cooldowns, this is bad. therefore a AMH system would be good.
