I fully believe that the powered up Thunder Hammer damage for both variants (the Crucis and the Ironhelm) should be (mostly) normalized, and that they should both have the cleaving mechanic the Ironhelm currently has.
Currently the Crucis has a higher damage, but only has wide horizontal swings and stops on the first enemy hit, while the Ironhelm has less damage but cleaves until the first elite, specialist, or monstrosity hit. With the enemy concentrations on Auric missions, I find it frustrating rather than skillful to use the Crucis. A lesser enemy that got knocked over walking into the right of your screen shouldn’t completely neuter your damage against high priority targets.
While personally I believe that the 2 movesets are different enough to warrant them having the same special attack stats, if there was to be a more pronounced difference between the 2, I believe something interesting would be that the Crucis has higher base damage, but the Ironhelm has higher finesse damage (these could be switched around). That way the Crucis has more consistent, strong base damage, while the Ironhelm has stronger weakpoint damage, but lower body shot damage.
I wanted to make this post specifically because of the changes coming up to the Thunder Hammers:
The Ironhelm does not need the change to it’s swing pattern. It’s certainly nice, but it already cleaves through enemies. Why does it need the powered up overhead, when that is something the Crucis desperately needs?
I’m honestly a bit confused on this decision, and at this point the Ironhelm’s attacks are better fitted for the Crucis’ special action more than it’s own attacks.
If Fat Shark is hard set on making the Crucis never cleave, than I believe it should receive someway to access the activated overhead attack. While it might still have some frustrations with enemy clipping and targeting, it would be far more useful on it and make it much more consistent.
I would also like to take a moment to address some potential responses to this:
If you do well with the current Crucis, that is great and I am happy for you. However I believe a change is still needed on the Crucis to make it stronger and more reliable against the mixed swarms that are commonly present in high tier missions.
As mentioned before, I believe that adding the cleave to the Crucis would not make the 2 hammers feel the same, as the Crucis has a better horde clear pattern while the Ironhelm has the overhead heavy 3 to target high value targets without using its special activation. However if that is still not enough, I believe some more nuanced differences, such as the finesse different, would be a better way to differentiate the two and would still reward more skilled players with higher damage.
