New Ornn passive is uninituitive, confusing, and inconsistant...

I didn't even realize what was going on when I played Ornn the other day, there was a green line? Turns it it's to upgrade their weapon, BUT HOW? I tried and tried. A right click seemed to do it, when they were in a certain range.

I had to check the scoreboard to see if it worked, since nothing told me it worked, I thought maybe I was building something for myself...

So then, Ornn has to upgrade his allies weapons himself, if he sees the Green line?. I guess that's easy enough. But sometimes I saw the Green Line, sometimes not. And sometimes they had an item I could upgrade, but I could not. Why? I don't know. Is there a cooldown? I looked for a cooldown timer and I couldn't find one. I saw a counter that said "2"!!. Does that mean I have 2 upgrades? All game or is it some kinda charge up stock system? Beats me, I just kept checking inventories for stuff I could upgrade since the game wasn't telling me.

And finding time to upgrade items was a pain, often they'd Recall while I tried to do it, or they just buzzed off. Did they even know I was trying to give them upgrades? Should I had told them? They didn't even thank me. What a waste of time!

WTF is this passive even?.. Playing Ornn is a pain in the ass!
