I saw this duplicate post in the PvP forums.
The first response was to trasfer to a PvP server if that's mostly what you are looking for. I would echo that statement.
However, I believe that some of the above ascertations, are of less concern than you might realize.
Yes, there will be a strong population of people doing event related activity when they do come around, but it doesn't stop people from multitasking and doing multiple things at once. I a couple of observations on a MONDAY (yesterday) of the last day of the most recent event (bounty contract week).
- Solo rated PvP queues were popping for about 2 hours
- Team rated PvP was popping for ~11 hours
- Regular PvP was popping constanty
- GSF was popping at least for a couple of hours yesterday (that I observed or was informed), if not the entire day
FPs on the other hand, have always been a mixed bag based off of times and whom/roles are in queue. If you are a DPS class, this becomes even more of a wait unless you get your own group together.
I am MUCH less concerned about the issues you identified. We have a very active community for all aspects of the game here on JC.
