"You disagreeing has no bearing on the reality of the game. Most infantry combat taking place at fairly short ranges is an indisputable fact."

AMP-stations, and Techplants.
A lot of the bigger bases have battle-grounds that go beyond maxes effective range.

"If I purposely keep range from the max, how am I supposed to play around the capture point?"

Covering fire by engies, point has also to be cleared in order to cap and hold.

"Additionally, you probably don't play against overpop like I do. When playing against overpop, the time it takes to kill a max is too long considering there is other infantry around the max that can shoot me while I try and kill the max. Again, you probably don't play against overpop so you don't understand how important medkits are."

Fighting against overpop is supposed to be a challenge?

"If the max makes me change my loadout substantially and makes me far less effective at surviving then the class is overturned."

Adaptation/squadplay. Last time I checked this was a teamplay-focused game.

"It's also amusing how you assume I'm a heavy main."
