The only real way i guess to find out if its worth returning, is either to use a free trial, or to resub for a month and see for yourself.
Everyone has their own opinions at the end of the day. Personally im just going to give it a bit more time before i return again, hopefully next time i do, things will have improved even more. The game isnt the same as it was when the NGE was first introduced, its definitely better, but its still not as good, again thats my own opinion, i had hoped it would be playable again, but i was too optimistic, though again, if i had given up altogether i probably wouldnt still be talking about it on here :D
