If you feel the site is rigged then don't play there.
First game I played in a while was the other day in a jackpot sng just for fun because Bovada was giving me lag trouble and this happens:
I had the AA obv.
It's hilarious and I see quads by far way more then any other network in my life but I'm not going to make claims that WPN is rigging it up.
To say the network is full of regs compared to Bovada is a fair assessment though because wherever their is rakeback and volume rake race leaderboards you will find a bunch of hardcore grinding regs (good and not so good ones).
As for blackjack nothing more to say except it's a pit game with a built in house edge that even if it is actually fair the vast majority of people are going to lose long term that they really wouldn't have to rig the shuffle to show a profit. People also bet horribly in live casinos with blackjack when they are degening around such as increasing bets when they are losing,etc... At times it works just as if you move up a few stakes in poker but over the long run bad bankroll management decisions in all formats of gambling are usually not going to end well.
If you really want to play blackjack online do it with the live dealer sites (5dimes has two of them and a WPN skin) instead of going up against a computerized program.
