I had a blast on my warrior as a flag carrier. Was it the best option? Well of course not, but for the reasons you listed it was riot. Nothing like beating the crap out of couple of allys on the way back to return the flag.
That said, I went a little different route and tried to maximize my speed where ever possible. I also stacked agility as my 2nd attribute (behind stamina ahead of strength).
The AGM is an awesome tool to have. I'd try to wait to pop mine until the 2nd or hopefully 3rd return, but that shield is insane when coupled with lifebloom.
I'd also HIGHLY recommend buying stacks and stacks of the swiftness potion (in addition to Black Label). With a little luck you'll catch one of the speedups in the tunnel and if you have a potion you can pop through midfield the Quick Cap achievement is super simple.
I don't remember my exact gear setup. I know i had the defias chestpiece and the leggings of the fang along with the Runic Darkblade (crusader).
Which brings up another little warrior trick. Don't go into the defensive stance. I know you get the damage mitigation, but you lose the ability to charge. Use your charge to your benefit when crossing mid. It's like 2 free blinks per crossings. When combined with crusader you'll occasionally get an added heal thrown on top of it.

You can't have the Seal of Wrynn as Horde
Like I said Runic Darkblade with crusader. It's your friend (500+ hits)
Speed increase on the boots.
+4 on the chest. You give up 60 HP, but you get 4 agility and 4 strength. Your AGM and Lifebloom more than make up the difference
The satchel of goods gear... It's up to you on the cloak and the waist... But once again... I wouldn't JUST stack stamina.
You are going to get caught. When you get caught you want to be able to win a fight getting out of it provided you've just been caught by 1 or maybe 2. If you've stacked stamina to the detriment of everything else, it's a slow inevitable death.
