With enough complaints and due to the fact its under development which means there is a chance, a small one, to have it scraped. Me personally dont like auto attack. How else they met the demands for auto-attack, the amount of complaints they get and feed back with current system. Again get enough people to complain about it they gonna default.
Since 1.17c coming out things can change inbetween 1.17c and 1.18.
Underdevelopment, they can go either way from doing it or not doing it and not gonna be a set determine fate ie underdevelopment means its gonna happen.
So those say no to auto-attack go seek others playing from around the globle and have them jump on board the "No to Auto-attack" petition.
