>>55955934>if I'm at 3/5 when the season ends will part 4 still pop up after I complete it?Yes.
>I just meant any sort of general advice like if I should be saving any particular items or stardust until higher levels or anything like that, if its better to avoid things like raids and pvp until I've built a decent team, etc.Depends on where you play the game. If you’re in a place where it’s pretty easy to find people to do raids with (e.g., NYC, Chicago, etc.) then it doesn’t really matter if you have good stuff or not. It’s a good rule of thumb in general to wait until you have a good IV shadow Pokémon before using stardust on it, but if you can’t find anyone to do raids with, you might wanna power-up some particular stuff to at least do 3-star raids. Even if you don’t plan on spoofing, you may also want to consider making an alt. account on a burner/outdated phone with basic counters since quite a few mega Pokémon (and on rare occasions legendary Pokémon) can be beaten by two lvl. 30 teams, especially with the party power mechanic. Pokebattler will give you decent specs on how many people you’ll need.
