The truth is, even at 11% loss for points clearing, bonus clearing and ronin (if it's half the speed, it would mean 5% RB for point clearing lost, ~22% for bonus clearing and Ronin is also around 42% RB total (so 21% lost), but as said before, you can swap inbetween so you never really lose out on Ronin as long as you swap to VIP by the end of the month.
That's still 27% lost if it's 50% lost on point clearing and bonus clearing RB vs VIP. I'm not 100% certain it's 50% however, it could indeed be a 35% different, or something along those lines.
In any case though, SilverVIP vs RB isn't the question at all: SilverVIP is for sure better, 11% vs 27% doesn't even come close - the real question is: is even WhiteVIP better than RB aswell? If the rate is indeed 50% for point clearing and bonus clearing for RB, then yes: WhiteVIP is better: 36% vs 15% (21% difference) vs above mentioned 27% would make WhiteVIP still 6% better.
From SilverVIP onwards, for sure VIP, would indeed be nice to get the numbers out there correctly, doesn't matter for me anymore though
already hit BlackVIP and obviously not turning back.
