what kind of operator would you like to see in siege? As in what would they be able to do?
an attacker similar to Thatcher but instead of an emp blast it's liquid nitrogen, freezes all the walls in the area making them destroyable with soft destruction ie: sledge hammer or breaching charge, could also make any defenders in the area move slowly for a couple seconds
if frost was attacking they could have done this tbh
A defender which could close some parts of destroyed reinforcements. idk if this would be op🤷♂️
