Using frag rounds to destroy ice crystals created by glacial bolt

This interaction feels extremely buggy. Even just a few meters away, you only usually destroy one wall (frag rounds are supposed to pierce 2 targets). It may be that the hitboxes of the walls are weird/off and/or the frag rounds aren't piercing the ice crystals properly? Either way, it's not something that "works" per se for mapping from my testing given how often you miss the wall (even at close range)

I didn't realize frag rounds had that interaction to be honest. I've just been freezing stuff and hitting them with frags. Seems to do enough damage that way as long as you have enough freeze buildup and use something like permafrost or escape shot. I wonder how well this would work with frost wall, then you don't need to change ammo types.

I gave the same feedback in my post, the interaction does feel extremely inconsistent and sometimes you'll aim directly at the frostwall and it wont blow up.
