Ya the bloom is what really gets me the fact that its in the game is honestly awful its just another way EA coddles new players and casuals. No scoreboard, no KDs, bloom, no all chat, SBMM they lower the skill ceiling and raise the skill floor so much what we have left is a dull and in my opinion not a very good game. Of course because ARs have always been versatile they chose to make them have the same range as SMGs essentially and smgs just do a 10x better job in those ranges so the meta is as such. I recommend you try the LCMG SVK, and PP-29 those are the meta picks you can make DM7 work and i heard the best AR is the last one Ac-42 i still need to unlock
