His actions just don’t make sense. Teach has been growing in power since pre skip.
Why is Shanks waiting up until Teach is at his peak to challenge him? If he was really serious why didn’t he do it during the payback war?
Why didn’t he help Wang Zhi?
Shanks seems to be just waiting for Luffy to do everything. That’s why he gave his arm for Luffy. He knew Luffy would be joyboy.

Despite the fact that we see trought the manga an exponential growth only of Teach's power and not of Shanks', in reality, Teach has always been on a similiar level of Shanks. This is implied in Shanks meeting with Whitebeard, when he basically begs Whitebeard to go and take Ace back, and says that the scar that aches the most is the one on the eye, inflicted by Blackbeard.
Just as Ace and Marco in the future, Shanks was also confident of beating Blackbeard, and the bad outcome of the fight shocked him.
While, due to the story being a Battle Shonen, it looks like only Blackbeard is growing in power and so Shanks is for no reason waiting for him to reach his peak before challenging him, I believe that Shanks is also growing in strenght (at least crew and alliances wise) and so he is actually waiting for HIMSELF to reach the peak, and he did now by forging an alliance with the giants.
Now he might finally feel ready to face his demons, surpass the eye scar ptsd and face Blackbeard once again.
