Has anyone seen the new Mage Knight 2 rules?
There is a rule there that I think would be terrific in HC, which is the Rule of 3. It states that no number of net adjustments can be greater than 3. So Perplex in particular would come easily under control.

Have we heard anything about a HeroClix 2.0?

I can't say I'm really anxious for it, but they have added several interesting things - characters can have two powers for one particular stat, they have fixed range damage numbers, attack modifiers that kick in in certain situations, and best of all, ITEMS that can be carried by certain characters like the Dungeon treasure chests.
