Let me guess...you either play exclusively on roflstomp teams or have forgotten how it was to play at lower levels w/o soft capped defenses. Shiver is great mitigation available whenever you want. It pretty much makes you and a squishy team without reliable hard control immune to melee. It increases recharge time of enemies by 3 times or more. Not even close to being trash. With your mindset; Ice is a wasted power set as the damage it does offer is (significantly) weaker than any other that isn't Devices or Tactical Arrow BECAUSE of great mitigating powers like Shiver.
lol. You are mighty defensive there over a pretty terrible power.
It is trash on steam roll teams. It is trash at low levels. It is trash with or without defense in your build.
This is what a build looks like w/o defense. Just go 3 shot a boss before you spend 2.5 seconds animating a power with zero damage and no real lockdown.
Without defense, the less damage you expose yourself to the better. Shiver still lets the mobs run through their suite of powers, it just slightly slows the time before you can use them a second time. Enough damage lets you do the same thing, with the benefit of having a dead mob.
checked your video...any chance you can share a link to those binds you're running so you get the countdown on the power button? that is tight.
