I did the 20 straight wins and even for that I contemplated just not doing it at all.
WT has always been trash, now it's even more pointless since the character pool doesn't include the more worthwhile units. Back in the day, people didn't have too many SSRs, so it was a way (still shitty) of getting a new one. Of course, these days there's always that random good luck pull that gives you a dupe you need, or something, but that's rare especially for older players.
But at least now we don't need to play it 80 fucking times to get an SSR, I guess.
In other news, it would be cool to have something drop this week but this is Dokkan and given the end dates of the current celebration, the new stuff should only arrive on friday. And the banners themselves even later.
If only there was some piece of DB content currently being very popular and making tons of money at a mass market for the game to take advantage of.
