Finished star chart and am caught up with all major story missions just wondering on what to do next.

I (at mr 9) Don't feel I have the necessary amount of Stuff (mods, mr rank, ect.) to attempt steel path/endgame content properly yet and was wondering on what to do to prepare.

To give an idea of where I'm at and what I could do I will list what i am missing. I need to level all my factions to max, I probably need to build more weapons for Mr, I need arcanes, I need the helmith section for arcon shards and subsume abilities and probably just more experience.

So please if any tenno are reading this some help would be gratefully appreciated
