By losing Defense for Strength, you lose both Defiance Stand and Last Stand, both giving you total of 6 - 8 sec of immunity to Death. If you trading out Shield for Axe losing 4 sec of Superspeed and another 3 second of Blocking/Heal.The DPS and Heal you get from Strength/Axe does not help you while you are in the middle of the enemy Zerg. Cutting down your survive time = no DPS. The DPS you lost will be buff by your teammate Zerg.With the same Class Stance Skills (adding Frenzy or Berserker Stance for Featherfoot) you can run full Zerker with GS/Axe2 while in Berserker Elite will give you Strongest Burst (personally from 10k-50k in 1-2 sec on a single enemy with not counting the 30K+ of AoE). Fgj becomes a 10k instant heal, with two casts, and you keep defiant stance. If you can't survive with that... =/ No one runs shield in wvw zergs, it's not needed. Wh offers group support while axe gives damage, those are the zerg weapons of choice for offhands. With strength, fried dumpling, and sigil of strength you heal for 1.6k when you crit. Whirling axe essentially makes you immortal if you have stability. For extra fun, use pack runes =D I am all for less lazy Warrior gameplay. Double EP and Last Stand are great crutches if you need them (and if you need them, then for the love of the Six True Gods use them), but self sustaining yourself while simultaneously buffing your allies is better. For the original build posted though, there is not much self might on the build. Martial Cadence may be a better pick to get your Leaps back up quicker for more superspeed. That or drop one of EP or BS for FGJ and keep the Phalanx Strength.Try it outThis build giving allies 100% up keep on Might as the fight going along, as soon as you switch to Sword/Shield mode. Which also heal you, as I mentioned.Zerg vs Zerg is a different story as to 1 vs 1, please keep that in mind.This build doesn't care about putting out most of the damage yourself. It mostly negate the enemy Zerg from putting out damage while your Zerg is bombing.The amount of boon striping you are putting out is worth almost 3-5 necro.You can mostly 1 vs 20 for almost 15+ seconds with the rotation I putted out.No damage from Enemy = More damage from your Zerg = More damage overall = Easiest Win of your life.A full squad (30-50) SHOULD NOT have more than 2 of this build as mentioned.
