There was this one game i had where there was this sejuani jungle in my team
We caught illaoi in the river 4v1 and decided to go onto her
3 of us spent our cd's to kill her but she managed to ult and started healing
sej didn't ult that fight and we got murdered for it
I told her that "i think it's wise to comit the ult for the kill sej"
she responded "yeah i didn't expect us to have that much burst"
Every fight afterwards she comitted the ult for illaoi and we burst her before she could ult and turned the game around.
The game was pretty much relient on sej ulting illaoi every time so that illaoi can't play the game.
We won that game Sej got all 4 honors. She practically 1v9d.
If it wasn't for what i said she would have probably kept fishing ults for their backline instead (which were useless as only illaoi was a threat) and we would have probably lost since we can't burst her through her healing if she ults.
So
perhaps your team mate knows better and you should listen
just maybe you will win the game off of it
who knows
im not saying you should be your teams bitch
but straigh ignoring advice on the basis "i know better" is one way to keep losing games where "it's totally my team holding me back"
