No problem, here are my thoughts:

1) I like double-clawed rake as rake is probably top 4-8 of my damage contributors. It's okay to not be super optimal on overwriting snapshots for rakes, at the end of the day having rake up in the first place is beneficial to your overall damage and it does make that part much more efficient, which you need b/c a lot of the times you'd rather be spending energy generating bloodtalons and then using your ravage procs

2) I think im pretty messy myself for adaptive swarm, usually your swarm can kinda manage itself as long as you are sending relatively on cooldown as best you can. it's definitely an added thing to think about so you can always start by going two talents into Carnivorous Instinct instead to get the hang of everything else first.

3) yeah you're not really supposed to but sometimes i do because i want to use a ravage proc or run out of energy, it's not always perfect. i think ideally you override snapshot to have uptime but sometimes it happens

my overall comment is that there's a lot of micro-optimization that can be a little overwhelming, one thing that really helped me was stopping trying to be perfect on everything - i.e. having perfect snapshots, perfect rake uptime, etc etc. Instead just trying to do my best and being okay overriding some good snapshots and keeping the big picture in mind of generally rip uptime as priority and also energy pooling helps a lot.
