In Dota 2, there is a small indicator underneath each hero portrait that will light up when that hero's ultimate ability is ready to be used. When the ability is on cooldown, the diamond is greyed out, and when it is available to be used, it he icon is green. This small feature could help teams to coordinate better without having to constantly alt+click their abilities communicate. One issue that I can see with this would be heroes with multiple abilities, and it could be somewhat inconsistent. For example, on Lina, it is obvious: the indicator would correspond with Pull, but with a hero like Hook from Banjoball, who has two separate hooks abilities (one for allies and one for enemies) this could be problematic. Also, for heroes with a special sprint as well as an ability (Invoker), or with a special sprint and no other ability (Anti-Mage), the effect is inconsistent. A solution to this potential problem would be to consider the ability ready (and have a green light shown) when any of the heroes abilities are available and don't consider special sprints as an ability for the indicator. Thoughts?
