Destiny Rumor Third Subclass

According to Tyson Green, Bungie Lead designer, rumored third subclass slot on each guardian’s character screen has another meaning:

“The reason why there’s that third subclass slot there, is that some people may recall that we used to have a mechanism for sealing a build and locking your choices in, which would give your build a boost. The game would let you make another copy of that build. That’s what the slot is there for. The game would let you make another copy of that build. That’s what the slot is there for. When you needed to make a copy of your arc titan build because you just locked the other one, we had to make room for that. So that’s why the third slot is there. It shouldn’t be read as a tacit promise, but the fact that subclasses are swappable should make players excited about the future.”
