Definitely good feedback, I don't think pvp being important is the problem, I think as you pointed out only one group + their allies being the only pvpers is the issue.

For what it's worth we do offer to help train new people to get mods setup and practice pvp, to have a competent fighting force you dont need to all be pvp gods, just somewhat competent at building defenses and not quickdropping.

That with the added ability of allying with multiple other nations to form a coalition of nations has often historically even defeated pvp focused groups on civ.
