Warning: I feel a kinda long post coming on.
I find it kinda weird that Party breaks their tables in that way.
In live tournaments, tables break in a pre-set order but the players aren't told
what that order is.
There are some practical considerations in live tournaments that mean you can often guess if your table's going to break early - typically, it's if you're sitting at a cash game table that's been converted just for the tournament, or if it's in an external location (the tables out the front of restaurants or in function rooms at last year's WSOP
, for example). But in theory
you don't know when your table's breaking. Stars obviously follows this procedure or something pretty close to it, with the added bonus that there's no such thing as a converted or poorly located table in an online tournament so the breaking order really can be random.
At certain stages of live tournaments (usually at the end of the day in a multi-day tournament, or when there's only a few tables left) there's often a complete redraw for seats too, so everyone
gets moved around. Even the feature tables can be broken like that. To the best of my knowledge online sites don't bother with this.
Also, even if you're on a table that's not due to break for some time, you can still be moved to balance another table. This should happen online too (I know it does on FTP), where your table isn't broken but one player is still moved.
So yeah... I really can't see why Party would do that when effectively you're right, it gives some players the unfair advantage of getting better reads on their opponents.
Almost every live tournament will follow the Party system of using a dead blind / button. You rationalise it this way: the big blind always
moves to the next seat, and if either the button or the small blind ends up in a seat that's just been vacated, it's just declared dead.
AFAIK, not allowing dead blinds / buttons is actually pretty rare - I'm kinda surprised to hear Stars do it that way. There's nothing stopping live games from using the rule FWIW, and I'm sure someone does it somewhere, but I guess it's easier online where it's automated. I know as a dealer that explaining the dead button system is hard enough. Trying to explain to players (especially novices) why blinds are jumping all over the place and why someone got to miss out on paying a big blind would be just nightmarish.
As long as the rules (on these and whatever other points you care to name) are applied consistently, it'll all come out in the wash. You'll benefit from knowing the table breaking order or missing your big blind as often as you'll be penalised by it. It's interesting to hear what they've chosen to be unconventional about though.
