I would say a large majority of players are not here to roleplay.. Simple as that. And it's not that Reckless has mechanics that encourage people not to RP because the exact same thing is happening on other life servers. Life has just been around for so long I think a lot of the every day players got bored of it, so they choose to just have gun fights for the action. You will never force players to RP because if they want to force an engagement they will plain and simple. The amount of "RP" has been going down on life servers for a long time. So the only real solution is to get rid of the players who don't want to RP but then in the end you are only left with the select few who actually do. And who wants to play on a server with a low player count like that? I know the whole 'RP' thing got bored for me recently which is why I've taken an extended break.
Just my 2 cents
