If I could just have 5 of myself in one team I'd probably breeze through onslaught 100% of the time
Every single game, there's at least one useless member
Someone with 2 augments
A sona who doesn't take cadence, rhythm, cascade, and concerto
A malphite who starts roa
A Yasuo who stands in melee range and tanks shitloads of damage
A Jinx who stands and delivers instead of even attempting to kite
And every single game, I have top dmg by a wide margin (e.g. 1.5mil with second highest being 300k)
I've attempted onslaught probably 25 times now and only beaten it once with 5 Yasuos, one of whom took 5 augments so I couldn't complete my 4 augment mission.
