Oh, NOW I am double posting, since apparently Modsyl saved me from it last time while I was typing.Fair enough.
Personally, I'd rather list:
1. All the dual-Assaults.
2. All triple skill weapons that doesn't touch the useless stuff (Ability, Crit, Double, Triple).
By this definition, Athena Lance shows up. Not sure if anything else does. I have never bothered to check. People have made such lists in Q&A, but they are now buried within the sands of time. And outdated.
Buuut then when you start going the path that adds new stuff, you end up asking should you also include decent Exceed weapons? Like all Assault/Exceed weapons. And then you're on a slippery slope, on the one-way road to adding up all the weapons and oh god how did this become so bloated this was supposed to be just a simple list and do I fix it?!
I swear that happens to all of my projects.
