Also, as a note, sometimes when I use my shield on a teammate and it passes through an enemy and would kill them, that teammate gets the kill instead of me. I tried it last night against bots with a friend, and she got the kill instead of me.
We put an Annie Bot to 50 hp, I shielded my teammate as she walked away and Annie was between her and the ball, and she got the kill instead of me.
The same thing occurred when trying to get blue buff, my teammate started it and got it down to around 150 HP, then I used E to move it to her through the golem, she got blue buff instead of me.
Any explanation for this?
