Well, those Namethemwhateveryouwant designs look great and I cant wait to get them into my Hand or both, especially with the planned optional addons and alterations, but I hope that there will be still other kinds of melee weapons as well.
Don't get me wrong: The idea is brilliant and quite unique, but having only one kind of melee weapons seems still a bit limiting. Stabbing is cool and interesitng, but whats with smashing with hammer like weapons or swinging something for area damage in front of the character? Also, it would get boring over time if stabbing keeps the only method of melee combat (no matter how versatile the damage types are).
So in short words: Great concept, but don't keep it as the only one for melee combat, please
