You have to try, then come back and give me your review, not because something "Sounds" bad its bad.
Warcry is mostly useless (at least to me) by the range of the Agro, and agro is not permanent, i used it many times and nearly didnt agro the enemy close to me, it was a bug of something i don't know, but instead of Warcry i use Counter Strike. I don't need to push enemies back, i need the enemies come to me and resist the the punishment until my team get rid of it.
After a while i started testing with different kind of skills, i change them a lot after each promotion, that who uses the same build promotion after promotion is a FOOL! so is not like i use unbowed in all of my builds, but i prefer to use Counter Strike instead of Warcry, and Umbowed instead that To the Death.
Having an opinion as all very well and good, but you're arguing for something mathematically inferior. It's like saying that you prefer having $5 to $20 and that it's just a matter of opinion. War Cry provides a minimum of almost 3x as much defensive value as Unbowed. For some reason, you insist on comparing War Cry only to Counterstrike and not Unbowed. Why? Because they both have Taunt in their name? Let me present it this way.
War Cry is a short-range, medium-cooldown guard generator.
Unbowed is a short-range, medium-cooldown guard generator.
I'm at a loss for why the two are apparently incomparable since War Cry does everything Unbowed does--it just does a few more things as well. What's more, Unbowed is on a longer cooldown and generates half as much guard initially. So War Cry is 2.66x better defensively at a bare minimum. Once you factor in things like doubled armor, taunt, % damage increase, and decreased Walking Fortress cooldown, the comparison becomes even more laughably lopsided. There's only one real thing for the Lego that Unbowed has on War Cry and that's the CC cleanse...which is unnecessary if you run Payback Strike as mentioned in this post, my previous ones, and every Lego guide under the sun.
Your logic chain seems to be Counterstrike > War Cry, therefore you take Counterstrike instead. And for some inexplicable reason, now that you've chosen Counterstrike, you can't take War Cry so you run unbowed. You realize you can run both War Cry and Counterstrike, right? In fact, the two have insane synergy. Counterstrike pulls in the map, War Cry lets you keep aggro on everything you pulled so things you've hooked don't get loose. Plus Cutting Words significantly improves the value of taunts.
Payback Strike is a completely different argument that I'm not sure you want to get into...so I'll just say that you're not taking Payback Strike to knock enemies back, as you mistakenly seem to think. Gods no. It's about cleansing CC. If you get knocked down or stunned, just tap Payback Strike and you're broken out at absolutely no cost. It's absolutely invaluable for tanking all the bosses on Perilous--which you can certainly do without Shield Wall (ugh, gross) or Unbowed. In fact, those two skills actually detract from your tankiness significantly.
