Heroe's Skill Bars

Does order of skills in Heroe's Skill bar matter?

What i mean is... does it matter which skill i put first and which one i put the last because of frequency of usage of same skills?

Don't think so. They know what to cast and when, and where. Atleast, they should :P

I believe heroes are set to use the skills with priority given to what's on the left.

Which is to say that when the AI is deciding what to do, they'll start scanning the skill bar for options starting from the leftmost skill, and the first appropriate skill they find they'll generally use.

It generally doesn't make much difference, although if you have a chain of skills in mind (Enduring Harmon/For Great Justice) there heroes will have a slightly lower chance of screwing it up if the first skill in the combo is to the left.

But they'll still screw them up, and do it frequently, so you're better off handling that kind of stuff manually.

Wondered about this before, would be very interested in knowing if it's true.

Try it out with some duplicate skills divided on left/right side, and see if heroes favor any of them more or if they just use them randomly. If they do seem to favor certain duplicate over another, try switch place and see if they change priority.
