Real simple, i don't think the current time of 4pm PST is a good time for the 5 hour server maintenance. No matter where we are in the US, its just not a good time of day. I am CST so its 6pm to 11pm for me so I only get to play for an hour or two and debate staying up late to catch an another hour after. Most kids and adults are all out of school or work at this point in the da (3-6pm). C-virus quarantine not in factoring in, that just means Tuesday is a no-play-day.
I would suggest making it like 3am on Sunday or just at a time when the lowest amount of players are on. Maybe keep it on Tuesday but have it start in the morning instead.
Just an idea.
