Just started the game and am looking for info on how to progress.
Which of the characters i have are worth building and are any of the Nat 3/4* worth using as fodder?
Should i pull for the current 4* healer or try my luck at other 4*?
Are there an y Nat 1/2* worth building?
Don't bother advancing tanks, you dont need em for now... and probably for a loooong time since you are at the beginning.
2)usually I advise ppl to not fodder nat3, unless you already t3 them, since you never know how good a bad hunter could get after a patch.
And even after that, it's better to sell em at mystery shop instead of using them as fodders
That's said, we all know that certain hunters will never be used. It's subjective, and you will find out those you don't like with the time, dont worry. In that particular situation just sell them, since dormitory space isn't unlimited and sometimes you have to make room.
For now keep them and start to understand their abilities.
