I hate Ice II with a passion, that's why I'm so glad it sucks so much for BLM that I could literally throw the skill away (from my hotbar)
I never saw it used anywhere since 2013 (because ARR was new and people were still figuring stuff out), but I don't really play SMN so I don't consider myself an expert on this x)
Just saying that I never saw other SMNs in df use it. Which doesn't have to mean anything, we all know randoms often suck.
But yeah, if I was tanking, I'd hate you using Ice II as well. Maybe I'm a bad tank, but I can't see shit when it is used. I have no problem with AoE circles from DRK, NIN, BRD and the like, only slight trouble with gigantic explosions from WHM and BLM, but Ice II makes all of my ground vanish and I hate it
