Thought it'd be good to give feedback here as well given the great support I received from Jason.
Long story short, played and made my first withdrawal, but it was taking way longer than it should. Jason was able to sort it out fast for me and responded promptly on CM so I'm very impressed by that. If I ever feel like playing RTG again (And oh I will), it'll definitely be here. Not only we have Jason at CM who will be able to assist on problems, but the casino offers great bonuses even after the first deposit bonus. Can't say either of those for most RTG casinos these days given that most are rogue and only they offer bigger bonuses than measly 100%.
My only fear as with most RTG casinos is that the bonuses have max cashout which personally doesn't bother me a lot as $1000 with a $50 deposit is still a nice sum (max cashout seems to be 20x?), but since all RTG slots have random jackpots .. What if I happen to hit one? What then? At other casinos the random jackpots are not effected by max cashout rule such as when you play Netent slots, but at RTG casinos that does not seem to be the case. While some random jackpots are few thousand at most which would be a good way to clear wagering and not be too salty about missing out on the huge win, there are some slots that pay 10k, 100k or even more. Would be disgusting to miss out on such a sum.
I doubt the above will change for any RTG casino out there but it's a good thing to be aware of it at least if you plan to play with a bonus.
