Once people are 315+, the only reason to equip raid gear (imho) is if they like the aesthetics of it because at that level, the benefits of raid armour perks are nigh on useless. Personally, I recently infused all of my titans' full 320 raid armour except helm and legs - already have the PS exclusive and new IB helms at 320, so saving the raid helm, and my legs are staying until such a time I find a better alternative and an infusion buffer piece) - my titan is still 320, but now it has a 320 Armamentarium, 320 trials arms (luckily a female titan so those arms don't look hideous!) to go with the 3 x 320 helms and (for now) raid legs at 320. Much much better! I hate the styling of the hunter raid armour, so that'll get infused as soon as I can attain the rest of the ToO armour set for that. The warlock, well, the raid chest is cool, but it just denies influence from any shader, so it may be IB gear/exotic chests infused with raid gear as a mix and match set-up tbh.
