Ice vs Mace APP

I find I spend more time on Mids than in game lately, tweaking away on builds. So, this is for my ill/cold perma PA musculature build. Currently, I have ice blast, frozen armor, ice storm and hibernate. I went this way with LM's thought on the attack chain. SW is about 1.5s recharge, 2s blast, 2.3 blind. It feels like i could lose the ice blast and not really lose any continuity of casting. Given this could be a by product of the trial lag. Bottom line, the build i am using works well. It could stand some tweaking with the latest patch, between the reactive nerf (ice storm can go imo), and the allowing of ninja and beast run in trials, i can drop my travel power. I have this newer build pretty much laid out, adding in leadership and the other shield i opted out of (cant wait for the 30yard shield alls heh).

Then I have this itch. I am just really curious about Mace mastery. I wouldnt really consider any of the others since the toon is more heavily focused on defenses than resists. This gives me the shield, poisonous ray and another perma pet. It really boils down to the two ST attacks i think. Numbers wise, mids has ice blast way ahead on dps. This makes sense. It doesnt reflect the -res from ray, or the achilles proc i put into it, or the added dps from the tarantula.

I know this is a bit silly with T4 warworks, t4 musculature, t3 reactive, t3 ageless, and t3 ion currently. Its more of seeing how much more i can squeeze out of the build on the cheap. I could still fit in an apoc and rag, but i dont have the inf to do so atm and the gains arent that substantial beyond the +dam.

So, to summarize, how does the poisonous ray/pet compare to ice blast?

One more thing, with the reactive nerf, is there really any reason to slot sleet for recharge? from my understanding the debuff is 30s, and im only really slotting an extra damage hit/chance for AH proc.

I should mention that the mace build puts PR at 6s recast. Can someone explain how the dots/debuffs stack, if at all?

The DoT will stack, the -def and -res will not as its flagged to not stack from the same caster.

I've been considering going Mace over Ice on my ill/cold too. Ice Blast is a better attack, but the majority of my damage comes from my pets so the added -res and extra pet seems like it'd be a smart move.

As for the Sleet thing, yeah, still get good recharge on it. It's not a nuke anymore, but its still a great AoE debuff.

I had planned to keep some recharge in sleet, but not max it. Currently its at 15s recharge, dropping the recharge enhancments, and just slotting for the debuff and AH proc, its at 18.5s with my global recharge. This isnt including the t4 ageless destiny slot. Is it worth the slot for that three seconds (less with the constant recharge buff from ageless)?

You can double stack sleet for double the resist debuff if I remember correctly. Also it was definitely way overpowered so I wouldn't consider it a nerf...

If you have capped range defense maybe you should look towards a resistance based shield instead of defense. I'm currently using leviathan and haven't looked back.
