Who are these "other wars" you're talking about? I don't know if you even checked the chardev I linked, but it's only AP in slots where I can't get more crit in a 1:1 ratio.
For one, any 24 warrior with decent gear (crit or ap stacked), has enough damage to outdps rejuvenation. This is not 5.0 anymore, rejuv doesn't tick 500s. On a rage dump you'll outdps rejuvspam any day, no exceptions. Add warbringer, pummel and possible other CC you have (bombs, belf silence etc) and you won't really have a problem killing healers. Well, I haven't had so far at least.
24 warrior is potential of doing so much damage that the damage itself is enough to rely on, you don't need lucky crits to rely on. The crits come on top as an extra. You don't have to crit a single time to kill a healer if you time your pummel and charge right.
Won't talk about balancing your dps set with stamina, as that's a positioning/playstyle question. Though in my opinion you pick up enough stam from the obvious bis pieces to not be a total glasscannon. Mail armor and having stancedance macros are helpful aswell. Oh, and rogues don't crit 2k's
Why is it that you think engineering is mandatory? I've thought people mainly have it for enabling the arguably bis +16pvp power enchant on cloak slot, that doesn't seem to be your reason so just wondering.
I understand, the rejuiv comparison was an over-exaggeration, but imho rage dumps are still not enough without critting one, or two times. A feral, or resto perma kiting you with travel often will outheal anything you have unless your able to crit over the hots, even with double time. In terms of killing healers, im talking about people who actually know their class, spec, and how to play, not pubs.
Pummel and charging is not enough, hundreds of times ive come to 200hp off killing a healer and then being rage starved after a dump, even when playing 110% perfect against a heal.
I try and maintain 2k pre buffing on my war for pubs, and as for rogues critting 2k, i mean a full opener, not single crits. Often after being opened on by a rogue im left with 400+ hp.
Engin is mandatory for many reasons, obviously an instant interupt, also the sapper charge + flame deflector, for that extra 600 burst when needed vsing heals before a bubble, displacer, or fear, and the creation of discombobs.
Im not going to go into my setup to in-depth but i standby what i said. As in wars that ap stack, or want to, i know a few.
I see your setup, its good, but what i said was only to give insight.
