I think that if everyone has a DMR then it is fair. If an entire team shoots at a Mantis or banshee then it will go down fairly quick. Vehicles are used, not abused. I think the banshee bombs should do more damage in the same blast radius. This will help even it out with the mantis. And the sniper should do more vehicle damage like it did in reach. That will make the bashees a little less effective.
