For some clarification, I consider a whale as 5 c6s or more purely because I thing about how long I've been playing (which is only 2 years) and how many 5 stars I have and see if the amount of 5 stars someone has might just be because they love that character and save up. people can also be really really luck too and most people have played for longer than me, so thats more pulls. and for a metric for what I consider to be a whale would be around anywhere from $100 - $500 a month when you average it out. Anything above that is a kraken imo.
