"I'm getting really weak.. Think I'm gonna.... ¡¡¡¡¡¡WOOOOOOWW!!! 3 new subclasses out of nowhere!! Thanks dying traveler friend :)" lol, sorry, that's how I figured on my mind haha.. Maybe you could make some changes in there like maybe on its dying breath (again) the Traveler sacrifice himself to bring all his power together and focusing on 3 guardians of each class (the new subclasses) these new powers combined all the power of all the subclasses into one new powerful subclass, with a new element "Cosmic". Sooo.. Those are my thoughts on that part, good luck!! :)
