YouTube’s great for a lot of those questions, but Ill answer the questions that I can:
No. Kind of. The devs rotate “sets” of endzones. A huge part of competitive apex is knowing which end zone you’re looking at and setting up in the “god spot” before anyone else. For pubs and ranked (maybe except pred) that’s not worth worrying about too much. Focus on team fights and rotations first
You’ll definitely learn by watching comp, but YouTube guides for this. Hodsic talks a lot about rotations in his vid reviews as well
That’s normal if you snipe a lot
Depends on how good you are at the game. I’ve noticed that the better players loot what they need and once they have ok stuff to fight with, they’ll look for someone to kill with the goal of taking their loot
Unless you’re pro, that’s not that important. About Octaine, he’s a one-man army with little team utility. Great for pubs if you’re very good. Not so great for comp or ranked.
