In the beggining of the match, Tryndamere isn't killer, but in the ending of match (40 - 50 minutes) if he has all items, he is unstoppable, his ulti gives him 5 sec to mega-wicked-hardcore-monster-kill :)).

I take always runes for critical damage, it's pretty ^^

Take attack masteries, because Tryndamere is very great offense char! I try defense masteries and runes for armor/magic resist for my Trynda-killer, but I was trolling very hard :/

If u killed some minions (80) and u already have 2 bloodthirsters => +80 dmg. Tryndamere need DMG to 295% crits DMG, when u meet this monster in enemy team it'll be like this..
Teemo- hey team Tryndamere spotted..
Team - ok, w8 there invisible we are going..
Teemo - one, two, ...SHIIIIT ruuuuun
"an allied has been slain"
NOTE: be careful about stun, blind, sometimes silences (escape) :)..!

I always take the skills with regard to the situation. Often I take 4 times "Q" first then "E".

So.. I know the feel, if you use the ulti, and somebody stunned you. It makes me angry so much!.. Exactly use cleanse kill them or use "combo" of you'r summoner skills. "CLEANSE" "FLASH" "SPINNING SLASH("E")" and ruuuun ^^.

Someone write to our team after the match - "Tryndamere won it", or "Tryndamere vs. blue team". It was only team play. So, play with team stay close, have fun :), and good luck ;).

PROS:
- "crit, crit, crit, crit, slain"
- very good offense
- spinning slash trought the walls

CONS:
- very easy to slain
- stunned, he haven't chance
