New Blackjack variant

A casino that I used to work at, which has a monopoly on the area has come up with a new blackjack game that has basically replaced all the 6-5 BJ games. I got the rule sheet from a friend who still works there and I'm just wondering what the house edge would be on this game:
6 decks
European style
3-2 payout
stands on soft 17
Split aces once, one card only
other doubles, you can split twice (3 hands total) and can double.
All player 21's & Blackjacks are paid out when they occur, regardless of the dealers up card
Can double on any 2 or 3 card total, soft or hard
player automatically wins on a 5 card total under 21
when the dealer busts on a total of 22, all remaining hands are standoffs.

Thanks!

It sounded pretty good probably.
Until that last line...
Dealer 22 is a push.. almost +7% to the house edge.
Do not play it.
It's actually worse than 6:5 crapjack (+1.4% to HE)
