1: the only reason i was even not on fountain is because nexus was as good as dead and zhonyas was up to (and did) keep me alive until the match was over.
2: gnars q damage didn't take place because my zohnas happened a split second before it hit, this can be seen when my ult stops channeling which is well before gnars projectile contacts me
3:regardless of whether or not i would have died anyways, the fact remains that i was alive when the match ended, my kdr was 4/3 when the match ended, kdr reflects on your ability to play a champion and noone should be reflected poorly for something that happens to them after the match ends and while theyre unable to act
4: I had two viable courses of action that may well have kept me alive, i couldve walked downward to avoid the taliyah damage and then exhausted gnar I then couldve walked west towards fountain by which time tal's wall would have disintegrated enough for me to walk around or I could have walked north towards taliyah and eaten a minion to gain about 30% of my hp back. In either case my surviving was about 50% on the long term but significantly likely for the short gap between the nexus death and the victory screen had i been able to act.
