Hi, I was doing a game today, and I tried tanking blue buff with Tibbers. Tibbers passive killed the bluebuff golem, and I didn't get the buff.
I thought this was some sort of missconception, so I tried it again, this time on red buff.
The exact same thing happened.
1. Pick Annie on SR.
2. Get to level 6.
3. Have Tibbers tank any transferable buff monster.
4. Leave him tank the buff but leave his aura kill the buff holding monster.
5. Look at both: your champion, and your buffs/debuffs. There won't be any buff.
I was using AP jungle masteries with MPen Reds, Armor Flat+perlevel Yellows, AP perlevel Blues and Movespeed Quints.
