I Don't See Why Anyone Plays This Game!

I've been using Casino Verite for 5 months. I've been playing 6-deck, strip rules, using a level 3 count more powerful than HiLo that is played perfectly with a tight wong out point. I've played 10,000's of hands and continue to loose thousands of $ playing green. The NO is 14280. Why play blackjack, a game with such huge swings? I've also been playing poker for 3.5 years and consistently win. Of course there are periods of down swings, but nothing like blackjack! I can't see why the casinos should care at all about individual counters? The edge an AP has is so small and the swings so extreme.
