High grift is about run for your life (cast blizz, meteor with slow time and run).
It requires skills to do high grift.

No Wiz will stand there doing freezing or stunning job.
Because you get killed 1-shot if you stand there.

I think Blizzard is better 'cause it covers bigger area.
Blizzard + slow time combo.

It depends on build.
Some can optimize their Hydra builds, each hydra can hit 150-170m.
Then i think it's viable. 2xhydra + slow time.

mine blast build so that's a given

0 because didn't play lol
