As summoner spells you can never say these are the right, it depends on your play style. I found ghost very useful together with my AS because it's much easier to catch an running enemy and give them 2 AA which give you the killing blow. But flash works as well. But when you take flash as an summoner spell you have to keep in mind that you actually already have a kind of flash, your E, but of course you can always use an extra.

Some people like AD runes on the mighty toplane king Tryndamere, but i think it is a way better to go Attack Speed runes at him because he's stacking up his fury, much faster when you have a lot of AS and more fury = more crit. That's a big bonus. At early level you are forced to take some risky plays sometimes. and trynda is REALLY weak at them IF he don't have a lot of fury.

I dont have many comments about his abilities but i have some tips i want everyone else to know.
You start with his E because at level 1 you dont have much fury and the E is good to stack ituo fast if you need it, and then it's the only ability Tryndamere have that deals damage. As the last reason why you take E at the beginning is because it's an escape abilty.

I played Tryndamere in a bit over a half year now so here is some tips and tricks i found useful, and i found every single one by just learning him to play.

#1 Never ever use his Q before your opponent is backed or if you're low. It takes away a lot of crit chance and you need that crit. You should also by the most of the time only use it when you just killed a wave or the next wave is in sight.

#2 His W is very strong at catching up enemies but also to annoy them. If you can see that enemy is just on his way to get the killing blow on a minion you can use it to make him fail that last hit or maybe 2 or 3 if you're lucky. Remember the enemy still get the damage reduction when he faces you, but he doesn't get the slow.

#3 Use your ultimate as late as possible but you also risk when you do that. try to do it as late as possible but still so you not die.

#4 Tryndamere' E is a very good way to get away from ganks and such situations, always make sure to not overextend without your E ready.

Farming is almost the most important thing at Tryndamere as his fury stack up. it doesn't matter how much you feed (almost) then if you hit 200 farm you can split push to the win.

Pros: Good splitpushing potential. Kills fast. Funny to play. Easy to farm as.

Cons: Have a hard time against champs with alot of CC. Easy to catch if abilities is on cooldown. No tankerino.
