There will be a nerf of some sort, most likely a cap on the shield damage bonus like Corpulent's:
"The additional damage is equal to 30% of the value of the [Shield] and cannot exceed 200,000"
That sort of thing. Now from a purely business aspect, they have NO reason to admit to the nerf until AFTER the Fusion has ended. Right now everyone believes this is a MUST FUSE (and it is for most accounts) so spending is gonna be active. I mean 2 Summon Rushes with the 2nd one being with the bonus fragments?
Plus we know that the final Champion Chase event will likely overlap with points for the Path Event for the Soul, more spending go go!
Then halfway thru the Path event, this will be the announcement:
"We discovered an issue with the scaling of Titus's A2 Ability"
Maybe we should start calling Titus "NFT" instead
