In the previous DLC, iron banner armor dropped below the max light (you had to ascend it with etheric light that you could buy in the iron banner), but trials armor dropped at max light. You could get your character to max light by playing either PVP or PVE which was great for all playstyles.
Currently, there is no way to reach 320 light by playing only pvp, however you absolutely can get there by playing only PVE :
* [b] You can get up to three 310+ legendary armor drops per character per week from the hard raid[/b] (possible from golgoroth, daughters, oryx) ..and up to [b]five[/b] 310+ legendary weapons from the hard raid (possible totems, warpriest, golgoroth, daughters, oryx).
* [b]You can't get any 310+ legendary armor, legendary special weapons, or legendary heavy weapons from pvp right now[/b] and you can only get *one* 310+ legendary primary weapon per week (and only if you can go flawless!), which is much harder than doing the totems in the raid!
I think this should be changed - Pvp players should have a pathway to max light if they only want to play PVP (via the legendary trials armor set for example). Getting *one* guaranteed 310+ legendary armor piece from 5 wins on a trials card seems like it would be more than reasonable (even if its much less than what you can potentially get in pve). Trials special and heavy weapons should also drop at 310+ for the same reason.
I mostly play PVE myself, but I have a lot of friends who prefer PVP. Destiny has always been about encouraging both playstyles and should continue to do so.
