While high rollers wouldn't care with that since it's just a peanut for them, they're more prefer to choose a game that has a low edge or high RTP% because they're want to win and hit the jackpot.
Not really it is as you analyze it, if you bet $100,000 and lose it, a 20% rakeback is good enough to ignore, or you are not interested it(!?).
Rakeback is the lifeline of many high rollers, it is the reason for marketing and VIP levels, if they were not important, would not be a flag in many casinos, a player who always knows what he is doing, always checks the rake back %, it is a mistake Ignore It...
Therefore, rakeback is only applicable if the players are playing in any games available in the gambling platform, am I right?
Meaning, if you're not doing any bet in the platform no rakeback will return to you? I asked this because there is a confusion pop-up into my mind where the cashback and rakeback are just the same only. Where if you play there is a return and if not, of course no cashback and rakeback as well.
