If you gonna make the so called "Noob War" server, then yes... Solo style will go fine. Otherwise, no. I have experience of this believe me, if you're serious about starting such server and you don't have a wide range of attracting scripts (people love scripts) then you most have a very PvP-comfortable map. So it's either to let the features attract users, or the smooth way of PvPing, by offering a great map that is specialized for it. I'm sure you do that, but as I said, of experience of owning PvP servers I can tell you got to make such things!
I'm giving you advice you should appreciate it and take into consideration.
