1st i started playing this game with trynd and after 5 games i learned almost everything about him, 2nd i am using same runes as you as trynd and in my opinion they are perfect, 3rd i dont agree with buying avarice blade and ninja tabi when you are new better invest in zeal and B. graves [ boots ]. when you are learning game 2x p. dancers are ok but when you will be skilled... i dont think so its good... in my opinion 1 is enough, :)

With Tryndamere, thats quite the opposite. After those items that i put up, he will hit for 700-1200 dmg critcals. So..nope no armor pen :)

Isn't armor penetration supposed to be better than crit damage?

- Bloodlust (If you must heal, but always try to keep it on level 8 for bigger damage and biggger --->critics<---)

Change to Critts or Criticals ;)
other than that, decent build and a +1 from me!

nice trind build... its the one i use almost precisely and i got mine from from another build so...? ill give you a +1 anyway
