The problem with Ground Stomp is what will you give up?
Charge? Less mobility, zero ability to escape from bad situations.
War Cry? Give up 60% dodge? Not a chance.
Threatening Shout? Nope.
Wrath or IP? Trading a Stomp for 50% DR? Not a good trade.
Some players on the PTR have used GS in their clears, but they have the Paragon and main stat to survive in the GR 125-130 range, and they’re still not climbing higher.
The build flat-out needs more damage and more mitigation.
For what it’s worth, I suspect that there’s only 1 free skill slot in the build, and I think that for most players, we’ll use IP there even without PoC. With 50% CDR, IP’s cooldown is very manageable, and it provides a much needed respite from CC. Remember, the higher we go, the more CC becomes a problem, even with the Juggernaut passive and a CC roll on gear (which, I might add, isn’t easy to acquire, and could make gearing for this build a nightmare).
I strongly encourage the developers to help address the CC problem via the 4-piece set bonus. Perhaps something along the lines of:
Each stack of Frenzy provides 8% damage reduction and reduces the duration of crowd control effects by 5%.
With that change, and the Juggernaut passive, we can better manage dangerous situations that involve lots of CC.
