Statics aren't necessary for the first few fights or for EX primals. You could absolutely raid through PF on some servers if you wanted, it would just be slower progress.

Some statics will pick up newer players, the newcomer just has to look like they're on the same page and are willing to respect the amount of time and gil others have put into progress. Many raiders have spent time and gil on food, melds, and reading about their job and the fights to try to improve and win. I think the only real struggle comes for players who won't do any of that but want a group that does.
