So...
There has been a lot of talk about what the new class weapons will be.
And at the same time there have been a lot of the same about the sword you see on some of the trailers.
So here is my theory:
Warlocks will get a Sword.
Hunters a Knife.
Titans a Hammer.
Reasoning?
Well they are pretty obvious really, since hunters have their knife, Titans will get a hammer in their new subclass, and warlocks will get the sword. And supporting this is that in the video of the sword we see in the heavy, it is a warlock carrying it.
Making them this way where they are very similar, they avoid any of them being better than the others.
I strongly believe that this actually is a heavy weapon. And this will work in Crucible also, since it will have a ammo counter, and you have to be in melee range to hit some one. That way it wont be just a bladedancing super. Since every time you press it you loose ammo, and also you wont be blinking around as much as you do as a hunter when blade dancing.
Sure it will probably be good in some situations in crucible, but honestly so are most heavy weapons also. And the fact that you need to be in melee will make it less OP sort of speak.
So what do you think?
For me this feels very likely.
I haven't heard any one else bringing this forth as a thought, but I may be wrong ofc. For me this feels very obvious so some should probably have had the same thought process.
***EDIT***
So sword is confirmed, and it did not say any class requirement, also we saw a hunter dancing with the weapon on stream.
This can mean that my theory is totally wrong (quite likely) or that you can use other classes weapons if you have gained them on your other characters, (unlikely) or the fact that this is just a test build and that's why he had the sword also. (also unlikely)
It was a theory and i was most likely wrong. :)
