No Genghiskhant, I understood perfectly well that you are not against it and also your concern about existing premium members. I just felt like re-stating how I felt about the effect of the perk.
@TheGrobe, in a 3 days/move game, if Internet connection is not available due to some reason in certain part of India after two days (not very uncommon), even if you had vacation days available, you could lose on time out if you were not a premium member. That's a reality.
Save for the no-moves-in-any-games restriction, you have the same vacation rights as I do, I just happen to be able to automate it. There's nothing unfair about it.
