I think it will be ok in the end. This just shows how much a Night Battle only queue is needed. I personally see this as not different from having a separation of RB/SB. Some players want more/different degrees of realism. Night Battles are a fact of history, and reality. If so many of the “Realistic” mode players are so vehemently against more actual realism in their RB matches, then let us have our cake too and play Night modes only. Give us AB/RB/NB/SB.
I will repeat my view that anything under 75%-50% “chance” of getting a NB while Opting into the NB queue is unacceptable. There is a switch now for a reason, we can go back to normal RB any time we wish. There is simply no reason to have the odds so low, or not adding a dedicated 100% NB queue (also, the queue times for Ground RB are instant, 24/7/365, no one will notice an impact from a NB queue.) Furthermore, since NB’s are going to be so different, and we will want differing tank lineups and presets saved, it makes even more sense to have a dedicated NB queue so we can adequately prepare to go into a NB with only the specific tanks and CAS we wish to use (very important for CAS as the list of NVD/TVD CAS is limited.) Some lower BR CAS have NVD/TVD while some high/max lvl CAS have none. It could make sense to bring these lower BR CAS simply for their NVD/TVD capabilities.

Side note from above about BR/Tiers that should be allowed into a NB queue (I say probably Tier 3 minimum) : Optional Night Battles for Ground Realistic Battles - #25 by W_Wolfe
As to your question about getting any Night Battles: I have still gotten 0 NB’s, and I have yet to find even one person who has seen more than 1 NB. And I have only found about 3-4 people out of hundreds who have even seen one NB.
Update on my NB point grind:
Typical responses in game (these are all queued/joined with NA and EU selected, to give as large a chance as I can):
That is 10 screenshots, one in the main in game chat. 0 people surveyed have seen a single Night Battle in all the Ground RB matches I have played today. Before even talking about seeing a possible two NB’s.
It is time for AB/RB/NB/SB, 4 separate game modes & queues. Night is a huge part of the past, present, and future of warfare. If the vocal Ground RB players should be allowed to have their all day, all the time, year round Ground RB Daytime matches, then we too deserve to have a queue for all Night, all the time, year round. We have the technology (NVD/TVD) what on earth is the point of having all this tech without the night?
