Skipping savage floors

I just finished getting my last few totems from ex3 and was wanting to get into savage. I was wondering if this late in the tier it would be best to skip m2s and m3s since I’ve cleared m1s and the gear will be outdated soon? I mainly just want the mount and FRU unlock. This late people looking to do fresh progs are few and far between so I thought it would be best time wise. Is the difficulty spike really big or is it manageable?
