i understand what you mean, but at least, you kill 16 trash and you get a named to pop ... how about when i kill 30 mob + and i dont see Kronos ? who should be on 12% or like you said 1/8 mob ?
I just think Kronos doesnt spawn enough, if he was really 1/8 or 12%, in my 8h non stop farming i should see him at least 4 time right ? actually 0 :/
It's like rolling dice every time you spawn a named. If you roll a 4 the first time, it doesn't mean you won't roll a 4 next time and thus have a better chance of spawning a different one. It's 8%, then 8%, then 8%, then 8%, etc. I've turned in over 60 ice/earth crystals (just to get rid of them) and I have never spawned Kronos yet. =\ Just bad, bad, luck.
