Fort dungeon changes

hello i just wanted to ask few questions about fort instance's because there is no enough infos about it rly.
so my questions are:

1. first of all did amount of ke u get from that daily now got higher or u just made clan skill/lvl a lot harder to make?
2. i see rb lvl got increased, but no1 said how much increased? what is now minimum lvl party members to enter(for example pt of 85 ppl was enough to do it but now?) ?
