ok let's wait and see
we do that since 2010 that l2 became Free2Pay
suggestions for starters
fix the server time outs
fix the random dc's
fix the dc's when porting to world special hunting zones
go back to previous maintenance time at least for Elcadia (we live in EU and server's time is friendlier to us but new rr time is extremely hostile)
and the biggest problem from all is the "close the client" little window after a dc
make the client so you can relog without having to run all the idiotic nc launcher sequence(instead of "close the client 7" to have relog access)
