Hotkey Issue

So I set my Item hotkeys to Shift QWEASD

Well, it works for almost everything, except enhanced marchers. No matter which slot I put them in, it won't cast. I mean, it will cast "occasionally", but thats after hitting it 50+ times and it usually happens when I don't need it. Runes work almost always, Orbs work almost always... But E marchers don't. The weird thing is when its in cool down, the hotkey always makes it say "That ability is not ready", yet right when the cool down comes off nothing happens. Anyone else have this problem? And is there a way around it? I think shift QWEASD is the best option I can think of but I am willing to change.

You're probably pressing the keys wrong, which is surprising for such a skilled RTS player.

No I found out my hotkeys work, but you can only activate E marchers while not doing anything. So I have to hit S, then Shift S, to get them to work. Rather annoying and the reason I don't usually buy them a lot.

i noticed that hotkeys sometimes didnt work while my cursor was at the minimap
