Good input, Semi.
From the looks of it, seems as if several forum posters can be correct in terms of PvP resilience staying on lower season gear. ( One reason perhaps the base resilience was moved up from 'all' to 85 and above' ) Subject to change, though doesn't seem like it would matter much considering that horrible scaling, Lol.
I assume there's a soft cap similar to the 66% soft cap we have now in this patch. Your Rogue didn't lose much resilience, but admittedly quite a bit considering you weren't even above 50% o.o
Should be interesting.
