Just my 2 cents from my perspective . I have two accounts . My main account is a day 3 account and strict 100 gem puller . My second account I started around xmas of last year and is fully free . My reason for starting a new account ? Originally it was just as a core only account and I wanted to see things in a fresh way as my main account is pretty stacked on gear and I am able to clear pretty much everything with minimal effort andor thought . Since the account is now nearly a year old I have some choice relics that I have gotten by being very frugal with my mythril on it . Shout , SG , and some BSB ' s among others but it still forces me to use different strategies to clear some content wether I go the core route or not . Especially more so with CM ' s . Personally , I find it fun . As for managing stamina and being efficient with it . I never care about stamina efficiency . I don ' t let the game force me in to it ' s schedule . In general , I burn all of the stamina in the morning when I arrive at work and then again when I get off work . When an event starts your just going to autobattle most of it anyway and then your left with only the 99 , 110 and 120 to clear which takes all of about 1015 minutes . Ultimates get done whenever they get done . There is never a rush really . If I can ' t clear a U fight on the alt because of any sort of time constraint , then it just doesn ' t get cleared and I move on . It ' s an alt account after all . Doesn ' t need to be taken seriously . It ' s still a mobile game in the end . All that said , I will concede that it may not be for everyone . Especially for people who like to be serious and try to minmax everything .
