Primal Forces Mastery - Thoughts?

I have an ill/cold/ice controller that is fun. I was playing around in mids and Primal Forces Mastery seemed to do something interesting things with power boost. I was curious if anyone here has any experience with this epic on an ill/cold?

i.e. with it on for 15 seconds: Endurance drains are massive, defense of all shields given to teammates goes up by an appreciable ammount, will recharge every 30 seconds with right IOs and makes capping defense to all typed and positional defense easy for a brief while, maxes defense debuffs, slows and so on.

Has me thinking....

To make it easier to examine this epic pool, check out this. This build is not a final build so don't waste time critiquing it. Instead, focus on how power boost changes the effect of pretty much everything. i have it toggled on right now but you can toggle it off and look at the effects. Like I already said, has me thinking....

Primal has a few benefits and a few trade-offs. While I don't have it on my Ill/Cold, I have tried it on several controllers including, for a while, on my Ill/Rad (I changed to Fire). The single target blast is OK, but slightly slower than Fire or Ice. The only AoE attack is a cone, which is not as good as Fireball, and comparable to Frost Breath (but Ice also has Ice Storm). The shield has the highest S/L resistance of the APP shields, but most folks are really looking for Defense.

Power Boost is clearly the jewel of the set. Power Boosted Ice Shields will help teammates who don't already have some defense, but won't provide much benefit to teammates who already have good defense.

Yes, it will boost the endurance drain of Heal Loss. However, my experience with Endurance Drain is that it is not all that effective as control unless (a) you can fully drain the foe and (b-1) you have a power to stop Recovery, like Short Circuit, or (b-2) you have a power that will continue to drain the foe, like some of the powers in Electric Control.

I went with the Ice APP on my Ill/Cold. Ice Blast is fast, for the Blind-SW-Blast-SW attack chain. Ice Armor is Defense rather than Resistance. Frost Breath or Ice Storm for AoE damage, and I love Hibernate as a great "panic button" power that lets me heal up in safety. Hibernate has saved me a bunch of times. Primal doesn't have anything like that. Ice also fits thematically while still providing a different damage type than my other attacks.

Thanks Local Man-Yeah that is pretty much how I have my ill/cold/ice right now. I just thought primal forces changes the set dynamics up enough to make it interesting. My current build is capped to s/l/ranged defense. If I get bored with my build, I might check it out and report back.
