Thanks for the link, I read the whole thread. You are approaching the situation from an idealogical perspective which I respect, but we really need to be more pragmatic.
The current compromise between allowing players to abuse the clock and allowing enough time for perfect decision making is extremely out of whack. Allowing a 5 hour game with base set cards alone is simply unacceptable. And you think it's not generous enough? Do we need days so we can hand write algorithms and return with our next action?
I do concede that certain kingdoms will probably require more time to play properly (on a competitive level) than I would like to allow for an all-purpose rated match. But again, there has to be a compromise. A blacklist is not an elegant solution, on the contrary it's quite blunt and dodges the problem altogether. So does banning people for playing within the rules of the game. Let that sink in a bit. Slow-rolling is playing within the rules of the game. I can't see how that is acceptable. Nor do I see how a ban is justified. There has to be a compromise. There were a lot of good ideas on that other thread and we can re-litigate those if need be.
Of course the clock should be customizable for pre-made games so that tournament players can have all the time they need. The clock need only apply to matched and rated games.
One more point...
An entire thesis could be written on the optimal play for any given kingdom. That's what makes dominion a beautiful game. Which by an idealog's logic would imply that we need infinite time otherwise we are limiting the player's potential. This of course would result in many games being resolved by who can leave their browser open longest...
Every kingdom is extremely complicated and ungodly lengths of time taken could be justified in making what others would consider simple decisions. To put it in words more elegant than mine, "AIN'T NOBODY GOT TIME FO DAT"
