I normally use TAB to upgrade my abilities because my ALT was used for something else, but using TAB gives me a problem: depending on the ability, it uses the ability AND upgrades it, which leads to awkward situations during laning phase or fights.
Some abilities that I can remember being used when upgraded with TAB: Mina's 2nd skill, Doorman's 3rd skill, Talon's 2nd skill.
Those are really important abilities that when used out of context can be the death of those characters, so unless you hold TAB and CLICK the ability, you will have to wait until you are behind an wall to upgrade it.
Which leads to another problem: I tried to return to ALT to upgrade my abilities, but ALT only works if you use the default 1, 2, 3 and 4 hotkeys. If you use a different hotkey (mine are M4, M5, E and F) the game doesn't upgrade it.
This leads to very frustrating experiences during some matches, specially under pressure in lane phase.
