There's 5 new missions every week and throughout the Act we'll also be dropping missions that support sub-events like Lunar New Year or April Fools.

That, in addition to Mastery based objectives and the Daily every day means there's plenty of ways to earn BXP.

Did you finish all your Act missions already?

Not yet, most are at 3 or 4 out of 5 steps. Yet the mastery ones are what bore me, forcing me to get S with champions I dont enjoy that much.

Guess I could blame doing aram, since it was what i played the most before swiftplay

You didn't like trying to get A/S grades on champs in ARAM? That feels like peak ARAM goal setting to me, personally.
