Im sorry but i disagree with this build.

Works well, (Never used Phantom Dancer on ap build, and it seems needed) +1

AP Trynd? Get serious...

i love this build :D

Ever consider guinsoo's? Ah w/e tryndamage op =3

Uhhh... What?

love ur guide.

This build is super awesome. Will it win you games? Probably not. Will you have a blast doing it? Absolutely.

Didn't work quite well.

This seems to me to be essentially the same as an AP Master Yi build. Complete burst damage with no sustainability and massive healing. Late game when a Tryndamere should shine will be useless with a couple magic resist items. You say late game you can 3-4 shot squishy toons, I can do that in 1-2 shots with a normal Tryndamere build. It seems like it could be fun in a lazy match with inexperienced players but in a serious ranked match, I highly doubt it is viable.

Freaking amazing build. Just amazing. I mean the damage to one shot minion waves is just ******ic, not to mention a 1k heal once your build is complete. This is so freaking pro, I'll never play any other champion or any other build again. It was love at first play. This Brandor guy deserves the Nobel Peace prize in geniusocity. I CANNOT wait for the next build to do.... Ive always wanted to see an AP renekton build, maybe this could be your next project??
KEEP 'EM COMING!!!
