We are going to need to add hero icons eventually, to put them on the ability infobox. Also, can someone with good wiki skills adjust the Template:Ability Infobox so the text is all aligned? Thank you.
And creatures/creeps/whatever you want to call them should be removed from Spells category.
This page should contain either a grid-like selection screen (as the dota wiki has) to easily select the hero you want to know more about, linking to their page, OR have a vertical table containing all the heroes and their summary information (stats, skills, and the like) which allows to know the needed info at the first glance but makes it harder to navigate. The choice should be made depending on how much relevant info the heroes will have.
