From my own experience, no.
Fastest GT2 drivers always go through corners faster than mid field GT1, brake later and have better exit but always some drivers thinking they are Lewis Hamilton try to pass them into the corners. That's generally fine but there are some tracks where it's not. I think everyone fighting in that first stint in GT300 in SGTS would agree with me...
I'm ok to have challenges but I'm not ok for a multiclass fest. Actually Fern Bay or South City are imo much better for multiclass as everyone is paying attention to everyone else. At KY2R nobody is that careful as it is a fast track and stupid GT1 drivers try to make some move in the last chicane or between t1 and t3 where it is just not possible. Trying to pass slower class on outside at some corners where you can do it (but still challenging) is awesome, but trying something like that when there is only one line is just stupidness.
That's my point, then ofc admins decide what they want to do with their league, and I will enjoy that race whatever the track they choose. Just giving my 2 cents as I think it's worth sharing it.
