Ice tiles require upkeep (quite a bit of it, lets be real) of FP from someone.

Voidgates require 3M (just like creating any ice tiles), and while they don't deal damage, they allow for proper repositioning and allow for a huge network that can be messed with by yourself to give you infinite black bolt spam.

Ice tiles require the ice enchant (or badge), Miu, Libergrande, famiuga, or some of the summon janky stuff outside of Verglas (and Verglas is basically FP drain central if you want to make a good amount of ice tiles)

I see your point though. It's just that in most cases for verglas (who are almost exclusively auto-hit central less they build otherwise), won't ever really have a desire to crit something, which is why 2m is "iffy". It lets them do an attack.. skate... and then not really do anything with the rest of their momentum.
