started pulling..
1. Europe - Nahida joined after 30 pulls. Spent another 30 pulls on weapon banner. No 5 star weapon triggered. Will keep pulling on weapon banner.
2. USA = as expected, lose the 50/50. This is my fourth straight lose across three servers. And I'm not even angry, because already expecting it (LOL)! The positive side is, Tighnari appeared on the first 10 pull. Which means Nahida is now guaranteed. Will keep gathering primos and pulling for Nahida. The new desert area is still mostly unexplored, gonna get primos there + Spiral Abyss + events.
3. Asia = 40 pulls, no 5 star character triggered. However, I'm expecting to lose the 80 (chance to lose)/20... err.. I mean the 50/50 here as well.
have been getting event banner characters only by guarantee for quite sometime now.

Baizhu / Ganyu banner will be rest time for me again. Not gonna pull there.
