First of all thanks so much, this is the type of comment i'm looking for, i will take most of (if not all of) them into consideration. I will defiantly work this information in. Second of all, i never mentioned health pots back every back, that's a really bad idea.

Few things:

• Guide Format: This is very important to a good guide. You want to make your guide as attractive as possible. As it is, your guide has some solid features, but really could use a lot more of jhoijhoi's help. She has written a how-to-make-a-guide-guide to help make guides more fluid and readable. You should check it out.
  
• Building health first?!: Tryndamere doesn't need to build health until the very end of the game usually. He gets his sustain from life-stealing on massive crits and careful use of Bloodlust. I'm not saying that health and health regen are BAD for him, they certainly aren't. Just that you have to build for damage early on, or people will just walk all over you because they're not afraid of you. As far as good health items go, for Tryndamere it doesn't get much better than Frozen Mallet. Try that one as your fifth, or sixth item depending on team comp if you REALLY need the health, but I use it more for the slow.
  
• Must....Have....FURY: In order to maximize your life-steal and therefore your sustain, you need to build fury as fast as possible. The two things that help with this: Attack speed, and critical strike chance. You didn't build either until deep into your items. Statikk Shiv and Phantom Dancer are the two notable AS/Crit items. They're both good choices for early Tryndamere. I usually build one of them after I have both Berserker's Greaves and a Vampiric Scepter. There are four values you can receive for fury generation: 5 fury for a normal hit. 10 fury for a critical hit. 15 fury from a normal hit that's also a killing blow. And 20 fury from a crit that is also a killing blow. With all crits, and a little ad (10 AD from Vampiric Scepter), you can stack 100 fury from one wave of minions...easily. There's no sense in gimping your fury production to the point where you have to auto-attack four waves to build a full bar. Get AS and Crit MUCH earlier to satisfy your need for fury.
  
• Um... Bloodlust is your best spell: Your skill order is a little difficult to understand. Spinning Slash isn't intended to do much of your damage each cast. It CAN do good damage if you get three or four of them per teamfight. You do this by reducing its cooldown, which you do by critting. Here again, you need more crit. IF (and that's a big if) you don't max Bloodlust first, and you choose Spinning Slash you are yet again hurting Tryndamere's natural aggression. Spinning Slash should be considered your utility or movement/gap closer. Bloodlust is where you get your damage AND your sustain...you NEED to max it first in almost any situation, except when Undying Rage can be maxed.
  
• You had mentioned buying potions with each trip back???: Um, you should have TONS of sustain from lifestealing those huge crits and healing for 450 every time you need it with Bloodlust. Tryndamere's natural sustain with his crits and Greater Quintessence of Life Steal is HUGE. You can steal half your health bar in a matter of seconds if they let you farm minions. Who needs more health when you're healing for 50 health per swing at level 9 and have a self heal for 450? That's monstrous sustain, I'd give up the I need more health idea.
  
• Try these ideas, you'll like the results!: I'm not saying your 'tanky' Tryndamere won't work. It does appeal to me for them to target someone else first, but if they have no reason to fear your damage, THAT'S why they're ignoring you, not your health pool. Tryndamere is a deceptive and fearsome champion who needs to do his damage to get respect, and this game is all about the enemy knowing you can kill them if they let you. Fat slow Tryndamere doesn't sound very scary...

Okay comment how useful this was to you here please, I need responses so I know what to update, and leave a comment if you down vote, otherwise i don't know what i'm doing wrong.
