I watched the first ten(ish) minutes, and what I came away with was that he's a bit clueless - or pushing an agenda.
1. No, you don't have to be one of those super lucky Cmdrs who has found an extremely rare pre-graded suit/weapon. They are all over.
2. No, you don't need to make your suit/better in order to have the ability to make your suit/weapon better. When you upgrade your equipment (which doesn't require an engineer), it gets better - the clue is in the word... upgrade. So there is no catch 22 there, just a very simple to understand system.
- upgrade suit at Pioneer (it makes suit better)
- each upgrade level opens a modification slot
- unlock engineers for access to modifications
So complicated, such a catch 22.
3. No, it will not take years to accumulate the materials. I'm close to having the materials for two of mods I'm interested in (for my super lucky extremely rare pre-graded Maverick suit). No grind, no specific material focus, just messing around with the new settlements, POIs, & occasional missions a few hours every couple of days.
