Board Thread:Plants vs. Zombies Heroes/@comment-5760976-20160422184712/@comment-27223432-20160509030730

Well... to maintain the current logic, if they add a new class for plants, they will have to add 5 new plant heroes (the same for zombies), to make a combination of the new one with each of the existent ones. I think adding new heroes with the same combination of classes we already have wouldn't make much sense, since the only difference would be one new signature power.
