Rather than continuing to debate whether 2x XP would help or hurt the server, why not give it a try and see what happens?
If there are still questions about how many actually want this on the pvp realm, we could always use the in-game pollsters. The one in this thread isn't definitive proof of a majority but I also dont think it should be totally discounted either.
I supported permanent 2x xp but even a 30 day trial of optional 2x (while keeping 1x available for those who prefer it) could be used as a test run to monitor player numbers, activity and retention to see whether it actually makes a positive difference.
I'm fully aware that there are concerns about optional 2x xp hurting the leveling journey but for the pvp realm specifically I think something different than the pve realm is very much needed and wanted to keep it growing. 2x xp would be a good start imo.
I genuinely hope the devs continue the pre ddos traditions of fireside chats, polls and community input so we can work together on building and preserving a stable thriving community.
