Hermagadon

Hello, I quit the game in the start of 2017, I forgot almost everything about the mechanics of the game so im not sure what should i even do when i hop back in. I am lvl 50 HM lvl 2 (Here is my char stats and gear i remembered about this web page that shows it https://bnstree.com/character/eu/Yoruichi shihouinn ), so if there is any kind people to tell me some tips and what should i aim for and what my path should be. Think i ended it on some quest where i climb some snowy tower and i need to jump to some other part im not sure what it was but i remember as soon as i jumped to that part the loading screen would start and never load and after like 20/30 tries of trying to make it trough that loading screen i decided to quit the game. Though of making new character first to play again trough the game and get the feel how the game is like now and then after a jump back on my lvl 50 Kung Fu Master but still i don't have an idea what to do after that.
