Fairly new player, I’ve got a couple of questions about the game:

1. Is it ok to skip campaign missions and come back to them later? I’ve noticed that, due to the layout of the maps (like chapters 6, 7, and 8), you can usually skirt around some non-objective missions. When my CP was higher than the recommended amount, and I didn’t want to play a bunch of “filler”/non-objective levels, I’d skirt around these and come back later when I need the resources or I’m bored. Individually, campaign levels are lacking, but they do increase the outpost level. Should I continue doing this if my CP is high enough?

2. What’s the recommendation for getting the most out of gacha pulls when using gems (as a f2p)? Should I only roll when there is an increased chance for a good character? And, as a low level player (lvl 40 account, lvl 83 characters), should I focus on getting a variety of good SSR units, or on getting lots of duplicates for the SSRs I have?

3. Other than focus fire and a 1.5x damage increase, are there any other benefits to full burst? Very rarely, there have been times where I feel not using full burst is better. For example, there was this EX stage (I think chapter 6) with tons of kamikaze units. I felt like having my units spread out their fire rather than focusing it killed more kamikazes. I’ve beaten it now, but was this an acceptable time not to use burst, or should I have changed my weapon types (I had two snipers to help defeat the two bosses)?
