People complain a lot about quickmatch putting them in (almost) empty servers, by lowering the amount that is needed people would be willing to stay and wait a little longer. I think when bf5 comes out and bf1 playerbase lowers down then it is also needed to lower the roundstart minimal player limit.
And for me with 4 servers - of which 3 run conquest - it would be easier to kickstart the servers. I think many rsp owners would welcome this. P.s. but focus of course more on the after round server crashes, i have had 6 of those in 3days so AFTER the june patch came out.
