I decided to throw the rest of my forma reserves on the Tonkatt and am honestly not disappointed. It's not a bad weapon, perhaps not "the best" but not bad.
Keep in mind, I'm no modding genius (unlike, HairlessPersian!) But throwing this build out there in hopes that someone may enjoy it. It works surprisingly well in the steel path. [Primed Fury] alternative would be [Berserker Fury]. And I played it safe with the "Y" forma as I know the geniuses will come along and create an OP Tonkatt build in no time!
Please let me know how you felt about this build, and what you'd do differently!
And please be kind, rewind.
Update
Replaced [Primed Fury] for [Primed Reach] and I feel that was a better. Again, would love to hear your input and share your build!
