Time to learn how to read. No one in this thread said schwerer should be on the front line. This thread was about it being destroyed even if it's back at a passive cutoff.
Im not implying this thread is about people putting it forward, im saying its a trend of normal gameplay and can factor into public perception of it being useless.
Before the most recent balance patches the FlakHQ used to lock down entire sections of the map, making it nearly impossible to push without a large devotion of most of your units that were subsequently suppressed and easy pickings for OKW units. It takes an enormous amount of effort to remove as it stand now or at least requires you to devote a large amount of micro, resources, and time to get it off the map.
If anything should be done I'd say an armor increase or HP increase to negate some of the damage might be okay but as it stand I feel like its fair and balanced and has fair trade offs with how its utilized.
EDIT: Also why make a topic if you seem unwilling to hear others opinions/make fair counter arguments?
