You seem to be basing your assumption on WHT's power being limitless and there is no tradeoff, which, IMO, is wrong to begin with, given what we saw.

Why Eren can shift upwards 3 times, and Bertholdt couldn't a second time when his life was in danger back in ch50? Because shifting takes toll on body, we know that much. Now, what IS shifting? Shifting is creating a Titan body out of thin air, through currently unknown means, but I personally lean over 'yeast' explanation. Regardless, hardening is changing the Titan skin into a solid material. Thing is, skin has to appear from somewhere before it can be changed. That means, WHT creates the matter it then hardens. One assumes, by the very same method Titan body is created.

Back to original point, Bertholdt couldn't shift again, because he had trouble producing that large of a body a second time over this short resting period. WHT actively creating stuff of hardening material, by the same token, rapidly drains its own strength, and the more constructs need to appear, the faster it will happen.

So no, WHT isn't OP by any means, and one assumes is vulnerable against the said Colossal Titan. You have to create something solid enough and large enough to pierce the neck and shifter inside to defeat it, and since you can't really use projectiles, that must be a spike-like thing WHT impaled Eren on during round one. A construct this large will most likely be the only thing you can produce. And if it doesn't get the job done - WHT is f*cked.
