Siege intentionally sabotaged by trolls! Please try to address this!

Riot, I actually like this new Siege mode. However, myself and 2 other players just went through the worst experience that needs to be addressed: intentional afks. Let me explain. We started off siege on defense. These two players never left the base. In fact, one of them disconnected, then reconnected before running around a few seconds and disconnecting again. Neither said a word about connection issues or anything at all for that matter through the entire match! Obviously, we lost quickly. Once our turn started for siege, both players "miraculously" no longer had connection issues and started playing. With barely 8 minutes to work with in all, it was nearly an impossible task. We tried to surrender and all 3 of us active players voted Yes. Guess who voted No to cancel out the surrender 2/3? Yep. These two trolls voted no to intentionally drag out this miserable excuse for what is supposed to be a fun mode.

1 afk makes it difficult enough, but 2 is crippling to a siege match. Especially if two trolls working together know this. I understand why 2 No votes override 3 Yes votes on a surrender in normal Summoner's Rift/Howling Abyss matches. But I believe with siege being such a different mode with emphasis on the timed rush aspect, I believe it should merit consideration where majority DOES rule. It can help especially in situations like this, but it is true it may not be the complete answer to this. 3 trolls for example would be impossible to override in a vote. At least for now, this experience has made me not interested in playing Siege again because I would rather not go through it again.

Is Riot at least aware of this? Are others complaining of similar situations in this mode? Are you trying to address this in any way? I'd be interested to know. Also be interested if the community has possible constructive ideas to improve Siege and help prevent this. I can't think of anything else at the moment. Thanks.
