I will not post a constructive feedback this time. This Jett revamp is garbage and you should be ashamed that after all the effort and feedback we gave to Nexon through many years, this is the outcome you came with. The main weakness points of Jett aren't fixed (bugs, 5th job skills not being strong or non-functional, missing 5th job boost nodes). This revamp was designed based on complains of temporary / bad Jett players that wanted to give a single button use to kill monster around at the cost of lowering Jett overall mobbing damage and nerfing Jett assets.
For players who doesn't know who I am, I was the first level 250 Jett / Zen of any MapleStory region. I quit my Jett in 2016 after realizing how GMS is powerless to make changes on their own unique class.
