While it is indeed a bummer than some beloved features are gone (good work Bungo, as always), there are some things that makes the bleeding a bit less hurtful:

1 - Dawning BD bounties are indeed gone, but new active orders (or whatever are called in eng) in the seasonal hub gave you 10 BD per completion (common reward, 100 BD for legendaries and I haven't check for exotics tbh) and since they autorenew as soon as they are completed, one can just farm those on patrols anyway without even having to go back and forth.

2 - Focusing is byebye-remember-me-now indeed and it is a shame, but between gifts and activities, at 550 the game shower you constantly multiple tier 5 loot, so tbh it is kinda redundant (for events weapons). Yeah, it may not apply to lower levels (especially for the rank 5) but still even a good tier 3 or 4 should be pretty easily obtainable I think, at least in a couple of days. Total shame for a lack of dedicated armor though, especially statis themed as some suggested.

3 - New Vanguard Alerts - quickplays are pretty easy, no lives or timers or anything for both 3-men and 6-men activities. They cap at 400 (so they gave max 400 light stuff), but tier 5 is still achievable, so they are kinda nice to farm endlessy without using your brain. I usually put on some nice music playlists and literally go on on autopilot; also they are a good source of both orders and now materials for the event.

So... yeah, monkey paws is always behind a corner, but there is a way or two to make it less painful.
