Since SA started months ago, I already noticed that past the 6 weekly SA, although it consumes no Stamina, it still requires the adequate amount of Stamina needed to start that SA (i.e. 30 for Difficult, 20 for Normal, 10 for Easy). So hopefully the dev can just change this aspect of it.

Another thing I noticed about SA is that after the 6 SA of the week is done, the 7th SA onwards will not give you a score to add to trying to compete in the SA rankings. Your SA ranking chance is limited to that 6 weekly SA.

I think the not letting you do the score was originally so you couldnt do an infinite free number of them to get a super high score. It resets each week though so..be nice i guess, just another thing to do, always root for that

the score isn't ac*ulative, it's the highest one you have ever gotten in that week, so that's not the reason.

Hey

Strong Approaching runs the same system that Instances do.
It requires stamina to enter, however since you've completed your runs, it'll refund your stamina towards the end.
It's been this way since SA was released.
Although I'll let the team know if it's possible to make it cost 0 for players who already completed their runs.
