If you have a Nasus in your team and the enemy ADC is fed

Stop surrendering.

Even a 15/0 Vayne can be taken down easily with a simple Wither & a fairly stacked Q, assuming her other teammates aren't as good as hers & not likely a threat. I've just finished a game where I, as Nasus, have not contributed anything to the teamfight(tried TP bot, but enemy top lane Trundle just being a troll with his damn Ice Pillar). At least let the Nasus players have some spotlight in teamfights to make a difference.

Of course according to that match, it was Liss who was fed. Not sure how much more I can contribute
