I don't know if any people are like me but I have been following testing discussions for
quite some time now and have often wondered why I do not post in there. My answer would be
because people understand how to play the game but are unsure of what to even say and or
do not wish to give input because they will get shot down for suggesting a idea that makes
sense to only them furthermore I honestly believe that 99% of people think they are not
qualified enough to give input or know the game mechanics enough.

as to the first half of your question(s)

Is it because you would rather gain exp on the main server? (A valid point, if that is
your opinion, please tell us that). Navyfield is broken in its current state but why would
people still playing this game care to give up their free time to help when they receive
nothing in return

Is it due to lack of rewards? Read above

Is it due to the account system there, and having to class all the crew? Could be, it
would be easier to designate accounts for testing, e.g. fully classed/equipped ships all
ready to go

Is it due to technical issues? I would say a big yes for me. Not everyone is computer
savvy and often worry about messing up their game just to try out in the test server

Or, are you just not interested (again, a valid point)? A lot of people complain about the
game yet are to lazy to help fix it so i would say another big yes for this one.

Don't forget this is just in my own opinion, nothing here is meant to insult anyone/anything

hmm some people might be afraid to voice their opinions for fear of them being shot down
and runover with a steam roller

myself i havent gotten around to dwnloading the test server
