Sentinel Epic Pools: AoE Immobilize

[Silverado]

I noticed that the AoE immobilizes that Sentinels get on their Epic Pools, Frostbite in Ice Mastery, and Fire Cages in Fire Mastery, prevent enemies from being knocked down. This is in contrast with those powers from Ice and Fire Control, respectively, which still allow the affected targets to be knocked down. This poses a problem for Sentinels (as if they needed more problems) when teaming with other players who may be using knockdowns as their main source of mitigation. If the Sentinel uses an AoE immobilize, they'd be preventing the mitigation and actively causing their teammates to take more damage. I bring this to your attention in hopes that it can be fixed sometime soon.

 

Thanks in advance.
