You have to give reasons why you think someone is wrong ya know

Just look at the stats.
Commando bren stats weren't touched by the latest patch.
Commando brens are insanely strong.
Commandos with double brens are insanely strong at max range because they have, as vipper pointed out, similar dps to obers even considering the fact that the stens basically do nothing at that range.
To that end, commandos with brens have similar dps to obers at max, but the commandos lose dps slower with model loss than obers do.
Anyway, given that you're still under the impression that vet 3 grens pack just as much of a punch at range as double bren commandos even though multiple users have said and proven otherwise with evidence, I'll just stop right now.
