When I started my Elementalist I used all my skill points on the armor thingy... (Didn't notice that Tome of Relearning thingy) So I had like no int or str at all. so I died epicly easily as loss of hp and dps in my spells are a bad combo. To get to the point:
The elemental armor is atm only useful in no chaos. (I read earlier posts about this but I have a suggestion that might be nice so don't get mad kay?)
In chaos however it does hardly count... Is nice to have first time you're there and so on. But my suggestion is so instead of making it 10+ armor every time make it INT based.
If you can make it so that you rather get 100 armor every 10 lvls like... You can't lvl the skill before 10 lvls have passed.
And if you have the know-how to code it from 1000 armor at lvl 100 to int based (Or you could just make it (xxx Armor + 0 x INT) until lvl 100 then at lvl 300 or something around that height you can continue to upgrade the skill.
However after the int basing starts, make it like probably start real low like 0.02 x int or something (Since int can become realy high that is actually a quite high number) and like... lvl it once more and it goes to 0.03 then add another 0.01 to that.
This will increase the usefulness of this skill tenfold. Cause when you think about it. Elementalists take so much dmg and have no dmg, except skills that without high enough armor to compensate for the CD you will surely die when the stronger stuff comes.
I can kill hell creeps and I'm lvl 675... but I can't kill more than a small group cause of the CD, when it CD's the creeps kill me piece'a cake.
Not going to make this any longer. If this is complicated to understand I will make it more detailed tomorrow... (1 am in Norway and I'm 13 so yeah shouldn't be up >->")
Thanks and goodnight everyone
