Don't jump to finishing act 5 as yet, that's not as easy as everyone puts it... Instead, you should try to focus on the uncollected monthly event quest... Complete it every month and try to get closer the the 100% until you can consistently 100% every month... After that, then focus on act 5 completion and exploration, by then you'll have enough 5*s and ranked ones to go for cavalier.
