Hello fellow BnS players,i had been playing BnS since the launch date and due to circumstances, i had not log in for 2-3years. My question is, 1)is it worth getting back into this game or is it too late to catch up?I played till the story of the game was " to be continued".Therefore i am an old player.Been playing even the story hasn't been completed. 2)Is there any major changes in dungeon runs and crafting? Is there anything new to learn? im downloading now as i am writing this topic. Kindly advise. Thank you.I appreciate your inputs.
