While I understand why people want to have more fun while playing their classes, I don't understand why people want this game to be a copy of an X game. If the combat/healing is more engaging for you there, just play that game.

I would like to actually see more innovation, a different approach, and a way to make things engaging. Also, keep in mind this game generally doesn't have the target audience set on people who have played every single piece of content for 11 years.

Making classes overcomplicated and with a zillion systems to watch for and manage will eventually just drive out a lot of "casual" players and some roles will see significant shortages. Healing by definition is the hardest job simply because you aren't just responsible for yourself but also for everyone else. Playing a healer is a completely different experience than playing a DPS for example in terms of how fights go.

PS: In case it needs to be spelled out, I don't mean classes should be braindead either.
