Regarding your remark about "it is their fault", I agree. But, for instance, I am out this week in Doubles because of diego36arg not sending picks even if we were +3 after day 1. And diego sent me his picks 2 hours after deadline. Of course, this should be exceptional (allowed only once in the tournament, and you could have penalties for that, eg. if you are tied, this should be first TB criterion before SRs) but it would help to keep the fun and be more tolerant with a player not sending picks (and not penalizing too much the partner). When I was in opposite situation, it is not fun for me to win by wo because one guy of opponent team did not send picks.
Sorry I really dont agree. If someone doesnt send picks I'd not like if a pick from his doubles partner will count.
I am playing these games since the beginning and I only forget to send picks once last week because I thought I am out.
Usually OOP is out early so everyone should be able to send picks on time.
And of course you need a partner who cares about the game, if so he/she wont forget to send picks.
