Attachment rebalance when?

Some weapon start with miserably small mag capacities and cost upwards of 50 attachments point to get them working at all

While the generic guns, you slap a few main ingredients on and you have a S-tier weapon

You have this system that allows some quick and easy changes but not a single one has changed which is odd

Just as a reference LMR27 (it's kinda **bleep**) but it's tbh the only DMR that if it needed 20 rounds it's this one, it cost 45 attachment points.... makes no sense
