I’m not sure if the new Frost Pillar is good,
in previously its main feature is to do grouping and minimize the AoE coverage, so it kill more with lesser skills. It is good to say previously for ET/CM you only need a Cryo3 and a good AoE DPS. the rest of 3 party members are lesser requirement. But, without the Cryo3, you need 2 AoE DPSer to cover larger area for DPS, and also a Cleric to focus more on the support.
Cryo3 is meta that made these content x2 easier, but without it a proper party is more needed. I think this is why IMC get rid of the pulling effect.
For new FrostPillar, it could become choke if not used properly, let say in Challenge Mode, you frozen some enemies in center, then there are some enemies outer range, you are actually preventing AoE efficiency if the new FrostPillar AoE is large enough.
