Im going to disagree with you. For starters, pvp and pve sandboxes are tuned separately and have been for a long time in terms of -weapon damage -weapon range -perk effectiveness -ability effectiveness so please dont use the tired nonsensical excuse that pvp balance somehow affects pve.. It doesnt, the pve community just uses PvP as a scapegoat for any issues they see in balance changes that occur for the health of PvE. Secondly, PvP and specifically Trials of Osiris kept destiny alive through content droughts, you might disagree with that but in destiny 1 trials of osiris was hands down the most participated in activity. Bungie themselves mentioned this at one point IIRC. As of yesterday pvp had 809k players and PvE had 911k so its still very popular

Sandboxes clearly aren't separate, but do your thing

https://www.forbes.com/sites/insertcoin/2018/03/09/destiny-2-is-finally-starting-to-balance-pve-and-pvp-separately/#b43b8c920f49 But if that isnt clear enough please take a look through the shadowkeep patch notes: https://www.bungie.net/en/Explore/Detail/News/48198 There are a plethora of examples of PvE and PvP balance changes being separate. In that one patch they tuned weapon damage for autos, hand cannons, bows and pulses separately in PvE,, They tuned damage perks like kill clip, rampage, swashbuckler etc SEPARATELY in pve. They tuned debuffs SEPARATELY in PvE and PvP they tuned super energy from orbs SEPARATELY in PvE and PvP Sure the core mechanics of the game stay the same but you have to be blind or intentionally ignorant to say the sandboxes arent tuned differently.
