People gunna complain that it takes a long time and that everythings being done from scratch blah blah, they did it pretty damn fast during Alpha, even completely changed the system from Alpha to Beta from our complaints and did many changes during beta, but now for some reason slowed down. Maybe because back then they had optimism and hope, something to look forward to (release day), now all they have is a product that is globally abused and disliked but they still have to continue working on it if they want their jobs.

A lot of things are just tweaks for example Auto Attack and Stamina, you're just removing functions that deal with how much stamina a skill uses and check if player has enough and then using it, you're removing the recharge of stamina, anything stamina related is removed and then auto Attack is planked on top which is not tough.

The only "start from scratch" i see is skills and such, which in some senses could take a while if they're doing all the skills but I doubt they are, attributes can be rewritten but thats just a category section and considering they did it perfectly fine in their last mmo they shouldnt have much difficult.

Developers say a lot of time they're doing overhauls or starting from scratch but you never do, you savour what you can because shit costs. Unfortunately for SE as they're just utterly rubbish developers (sorry but they are) and its all cocked up from the ground up things just take 25 years longer than usual because I honestly think they dont know much about what they are doing, its still a learning curve for them.
