So is this game going to set it up so the Holy Trinity roles are required to play through endgame? I liked the way Champions Online didn't put too much emphasis on it and you could play as a hybrid which the developers did encourage on how to play Champions, as a hybrid not tied to a specific role. Like what if I wanted to make a very high survivable and durable melee character but didn't have any means to grab aggro or generate threat and just wanted to be very tough to kill.

It's going to have more roles than the trinity, from how it looks theres going to be multiple viable types of support so you can take a buffer and become tough enough to not need external healing, and every archetype to an extent is a hybrid with maybe a couple exceptions.

So, roles but not trinity.

Mmmm. MA/Regen scrapper. <3
