Anti-AOE Orb (item suggestion)

[unormal]

I would suggest adding an item that has the same general cost/power level as Null Stone, but blocks one AOE ability on a hero instead of one targeted ability per cooldown.

As far as reasoning, I think it's odd that you can directly counter a targted ability with an item, but if your opponents abilities are primarily AOE, you're SOL as far as a potential counter is concerned.

Sounds good. Increasing the number and variety of items will do a lot to balance out many of the issues to say nothing of creating entirely new ways of doing things.

If your opponents' abilities are primarily AoE, you'd benefit more from buying a mekansm than blocking a single AoE ability. This is more of a greed item than a team play item; sure, you don't take damage, but your team still does.

Blocking on target spell is strategic for use on carries who will be focused, adding to team play; this, however, is counter productive IMHO.
