@Tilarta Just to hear, what is the stamina refresh time in your server?
As well as what you get from the bonus stamina times and get more stamina?
In server 5 the stamina refresh time is around 19 seconds at least.
The bonus stamina is 1260 and for the buy more stamina it is 720.
So this would probably be the way to go about it math wise:
((60 x 60) x 24) / 19 = 4547
(1260 x 3) + 720 = 4500
Week and month stamina wise for each of them.
4547 x 7 = 31829
4547 x 28 = 127316
4500 x 7 = 31500
4500 x 28 = 126000
So if this math is right we in server 5 get about a bit over a 1000 stamina more stamina per month through the stamina we get over time than the stamina we get at bonus times and through buy more stamina.
While not a lot it is still something.
.
But yeah, buy making sure to always use the stamina you earn over time and the bonus time stamina, as well as the buy more stamina option you should earn more in the long run.
While this server 5’s numbers, the maximum stamina server 5 can right now earn per month(28 days) is around 253 316 stamina when not including the Weekly Quest stamina.
According to earlier comments this should be around enough to get a character from R0 to R10, even if yes you Tilarta probably earn a bit less, but I imagine maybe over 200 000 stamina per month(28 days).
You could probably get it earlier than 240 000 stamina if you combo grind, but yeah can understand if it is a bit too tedious for your taste to do often, but maybe try to do now and then when you need badges from these stages or you feel for doing an extra push :-).
