What talk is there to dismiss?
It was pointed out by someone that the flags were attainable in the armory for more credits than they actually saved. The highest saving USED to be CVs when their base Tier X Service Cost was 360,000/battle (36,000 credit savings). That did get altered down after the Premium Consumable change standardized all consumables.
Was quite sure Tier X CVs were altered to 240,000/match, but I just tested across Co-Op (baked in 25% reduction) and Randoms which showed 180,000/match for my Audacious. So, the flag would be currently worth 18,000 credits/match, which isn't very much.
Further, the flag incentizes only Tier X play to try and maximize the return on it, as opposed to just playing whatever you want to play.

As for allowing Service Cost Reductions, there are permacamos, equippable camos, and clan bonuses which all reduce Service Costs. That's all still a thing~
