Just gonna make some suggestions for Ice Armor, specifically stalker ice armor. Stalkers get Glacial Armor (+E/N defense, DDR, +perception) at level 28 which is way too late compared to other sets that get their main shields much earlier. It's pretty much impossible to run a synapse TF with toggles on because of this. Ice Armor also doesn't get any endurance drain protection and there is no way to combat it except for energy absorption which is acquired at level 35. This makes Pen Yin TFs a nightmare because of the endurance and recovery drain from the Super stunner freakshow bosses. Carnies also destroy, especially when you're eliminating 6 minions in one blow which drains all of your endurance from their death scream since it's unavoidable. I propose that Glacial Armor should be switched to the level 16 T5 slot and have a small endurance drain resistance of 25% or so added to the power.
Chilling Embrace can then remain at the T7 or switched with Permafrost to be the T6. Permafrost could also use an adjustment. Maybe adding some more damage types to its resistance such as energy and negative or smashing and lethal. I have skipped it on my ice armor builds because without it I'm still sitting at 105% cold resistance which is 30% over the cap. The slow resistance from permafrost is also redundant because Ice already gets quite a bit and the winter sets can easily push an Ice Armor build over 125% slow resistance which I'm pretty sure is overkill.
Anyways I still love the set but just thought I should make some reasonable suggestions. Let me know what you think.
