Well, remember that you now get 1 stack for each enemy hit by Charge. So, you Charge 1 time, through 5 enemies, you get 5 stacks. And, with the Charge: Stamina rune, we’ll also get at least 65 Fury from charging those 5 mobs (15 base + (10 * 5 mobs)). More, if you’re using an ability like the Animosity passive, or the Templar’s Inspire.
Assuming you’re hitting something with Charge, the least Fury you can generate per Charge is 25 (15 base + 10 from 1 target). That’ll also give you 1 R6 stack. The Fury pool sizes you might have are: 150 (base + paragon), 162 (+Pride of Cassius), 170 (+Animosity), and +182 (+PoC and Animosity). So, at 25 Fury per Charge, it will take 6-7 charges to fill your bubble, at which point you’ll also have 6-7 R6 stacks. Even if you count a bit of extra Fury generated from taking damage, casting WC + TS, using Animosity and/or Inspire, or refunds from Arreat’s Law, you are only rarely going to run into a situation when you’ve got a full Fury bubble, but not enough stacks.
Stacks will almost always generate faster (and be spent slower) than Fury, at least when using Boulder Toss.
Haha, you keep your STD away from me!
I think that in a push, against a no-adds RG, or a “summon adds below x% life” RG (Like Saxtris or Binder), you’ll want to start the fight by just stacking Stricken with Charge for a bit.
