There's been some discussion of creating a heavy pierce sword here on the suggestions forums, as well as the need for spears/lances to be introduced. So, I present to you my solution for both of these problems, with my own spin on the idea of course:
The Spiral Joust

Combo: Would use the same animations as the Flourish's second and third hit in its combo, however much more slowly. There would still be a step taken between the hits and the majority of the attack would be directly forward. To balance out its precision and slowness a little, it would still hit things a little bit to the side of the thrust.
Charge Attack: A two stage attack. First hit would use a sped up animation of the Troika line charge attack, but would keep the Knight rooted in place. This hit would interrupt nearly all attacks and "stun" monsters without giving them the actual status, setting up the next strike.
The second hit would boost the Knight forward, cutting a swathe through the monsters in front of them and scattering them. This attack would have the possibility of striking multiple times against an immobile target, but due to the need of charging and executing the first strike, may be too risky to pull off in most situations. This second hit would use a lengthened version of the Flourish's final combo animation.
Names: Something I hadn't really thought about, but here goes...
3* - Spiral Joust
4* - Reinforced Joust
5* - Rhongomiant <= spear of King Arthur
If there were to be 5* variants with different status effects similar to the Flourishes:
Gáe Buide (“Yellow Shaft”) - Stun effect
Gáe Derg (“Red Javelin”) - Fire effect
The names come from mythological Celtic spears.
Stats: Admittedly, stats aren't really my area of forte. :/
Strength wise, it would have to be as powerful, if not even more, than the DA, GF, and Troika lines. This is due to its narrow attack range when compared to the other heavy swords. Plus, I'm not sure what would work better, split normal/pierce or pure pierce. Hopefully someone can come up with something better.
EDIT: Split normal/pierce is better. Wish I was smart enough to figure that out on my own... >__>
---------------
I feel kind of awkward posting this while there are other heavy pierce sword and spear/lance threads out there, but I don't feel replying and posting in those threads would get the same amount of discussion going as creating my own thread for this idea. Especially since a lot of said threads consist of one sentence "ideas" that don't help to really suggest anything.
Well, that's my hope anyway. Let me know what you guys think.
A heavy sword for piercing sounds fine, poke poke
Now i can stab thunderbog :p
