I have made similar thread on freeze mechanic in the suggestion category and can’t help creating a new one since it encompass a larger topic. I can’t express this issue well enough too, so please bear with me.
I have been levelling cold sorcerer and man, I feel that ice as an element is shafted compared to fire and lightning. Ice feels so detached from the rest of sorcerer’s kit with limited interaction.
Lightning has no need of elaboration on its OP-ness and fun with trigger-happy interaction between lightning blast, aegis, disintegrator, static, shock shred and so on
Fire has flame aura, dot ignite, flame reave, meteor for huge damage, firebrand, fireball shred etc and they can synergise with each other well.
Ice skills seem to be very standalone, glacier being the damage in front AOE, ice barrage being damage in front line, black hole for cc and damage, sharterstrike for OP melee. Only glacier and shatterstrike with 0CD. The interaction between the ice skills is basically stacking damage skill and frostbite. There are cold conversion node but the skill are mostly underwhelming by themselves. Personally, the balance in the skill node are also quite off with obvious best path. For example, chill node is not great with small increment per point and sometimes far from center and it is easier to get via affix. Chill also only stack 3 times, making it unnecessary to have so much chance on.
Idols in those two elements can be modifier to the skills while for ice they are mostly used to increase damage that seems to highlight the need to boost damage of ice element. Like where is the chill on hit idol?
Even the passive have more emphasis towards fire lightning solo/combo than ice.
The unique I have seen for ice are far and between and mostly deal with +damage, +frostbite,+freeze. Frozen tundra effect is underwhelming.
Now, I am not saying that ice is weak. It has good damage and its ailment is stronger, albeit harder to proc. But, I am talking about the fun in building an ice class. Currently it is a very straightforward build all skills for its highest damage potential (or freeze) and stack them.
Hope the revamp in 0.8.3 touch some of this issue. I have high hope for runemaster class too.
