First off, making XP carry over to the next act if the cap is reached. Swapping all instances of Rally Banners with 5 raid spoils. Seriously, why are rally banners still a thing in general when campaign banners exist almost everywhere now? Just replace all raid/dungeon banners with those at this point! Return seasonal legendary weapon ornaments as season pass rewards. Unlocking the ornaments for the legendary weapons was a nice reason to rise up the pass. They only stopped doing that iirc because of sunsetting, which isn't a thing anymore, so there's not much of an excuse not to bring them back. Replace some of the useless/too easy to get rewards like glimmer with things like some of the new eververse cosmetic effects. Additionally, add some of the other ones that normally are only available via eververse for around 400 bright dust (IIRC). There's probably more things to replace/change, but there's all I can think of for now.
