I wondered that myself,but saw that Elementalists can get a boost from Cyro down the line,so I went that direction when I played since my path involves it later on.
I will agree that it’s harder to control.I mis-aimed a number of times when I was grinding and the attacks completely missed.But it got easier to use closer to the end of the test,and I’ll most likely pick it again and may consider pyro too since we can do that now.I would recommend giving it a try at least.
