I feel dumb since no one asked... but what is the trap with Glacial Spike?
On another note: how is Comet Storm single target compared to Glacial Spike? I'd say it's hard to compare since the GS damage is pretty unpredictable with Black Ice proccs - are there any insights available?
I like how Glacial Spike feels gameplay wise, but am really uncertain how all the talents affecting Frostboltdamage (and thus icicles) work into it.
Does a procced UM FrostBolt increase the stored icicle and resulting Glacial Spike?
