The great thing is there's Reward Loops for each subset activities
Yes grinding and doing same activities will get tiring, but the Loot aspect is now more rewarding cause each feeds into the other
Earn tokens and destination materials, use for Rep Rank Up packages through Lost Sectors, PTE, HVT, Adventures Raid, Strikes, Crucible
Use Legendary Dupes as Legendary Shards for upgrades and Xur Currency
While all that's happening ever level up after 20 earn a free cosmetic Engram that you can earn more rewards
So grinding pays off, casual still can catch up cause the cycle isn't vicious at holding multiple currencies and materials
Hardcore get more out of it in the long run, but casuals don't feel "left behind"
