I'm still new to the Second Coil but have done a few runs of T6 + T7 (no clear yet)
I have experienced the, "hey learning pt awesome. Oh its T7, but I haven't finished T6 yet this week (or at all XD)."
I feel T7 was easier than T6, mainly due to T6's chaotic nature i think ~ Random one person focus.

My opinion will probably change when I someday see them on farm status, for now though … /sigh
