You took the Force APP and no Force of Nature? I can see that you're trying to stock in defense, but I just think that Force of Nature will do more for survivability than cobbled together defenses. And unless you're going to rely on PFF, since you don't seem interested in Force of Nature, I'd wonder why you aren't taking Cold APP in order to have a defense-based armor along with the heal of Hoarfrost. Then your armor bonus would stack with your Weave bonus although I'd see if you could add some slots to Weave to fully slot out the defense bonus.
Wait, I missed Tough on the first read through, but even so, why bother with the fighting pool if you aren't going to slot it out? If all you have is a couple slots to spare, I'd look at medicine pool or look at how you can add the tier 4 of your APP because I think it will help you more. I'm basing that off my fire/MM who has teh elec equivalent, and it makes her a mini-tank mage while it's on.
Ok I goofed around with mids a bit while on my break. I came up with this. I added a little more ST punch with -rech build in to help take down Boss types. I lost some ranged defense but still have over 40% Def.

One thing to note with snowstorm - it is a huge endy hog. That being, said, I have it on my fire/ice and really like it. Just be aware that unless you have a lot of endred built in, you'll run out very quickly using an unslotted snowstorm.
Hello blaster community, I come with yet more questions
Mostly I want to know if I've missed the mark with my current build? I group probably 40 - 50% of the time currently with my blaster. I'm not sure why I've been soloing with him so much, I guess because I can. Currently He is 25 and a load of fun to play. With a double exp weekend looming I'm looking to get a final build together. Thanks for any help, you guys n gals all rock .. but you knew this, didn't you ?
