At least we don't have to worry about mortars💀

ROFL

I like the maps where you don't have to worry about rocket mortars/helix racks/javelin 

While I understand that, especially from people that don't like those specific weapon systems (much like my dislike for em rifles), none of it answers the base question.  :(

You may try another tactic! The game is diverse, it provides diverse Content, including diverse Weapons, Mechs and Maps. Although the new Maps may be not good for some Weapons, that's when another part of the Content may be quite useful!
