I personally think it is unfair on players like myself you use to play these tourneys, (eg. daily dollar). I will pay for 1 enter, but certainly not 4 like have seen.
The other day I sat and watched the leaderboard of a rush tourney, (a by demand 1 i think it was), and by the time they were half way through, the 3 leaders had only entered the tourney once, I also took note that a lot of the players that had multiple enters, were out.
This comes as no suprise really, proberly a lot of fish looking for a quick fix.
