So since I have seen on the internet how upset people are about seasons 5-8 of the winx franchise, I decided that I would soon be working on my own personal rewrites of those seasons and a lot of things have changed. For example, my fifth season won't have 2 transformations and the main form is now only Sirenix and I might give it the Harmonix designs but changed slightly according to each girl, and for season 6 I have also mashed up Bloomix and Mythix into one form but that's it, I don't have any meer ideas for it. So what do u think I should fix in my rewrite for these seasons and what she be kept of completely adapted out.
