What spec has the most satisfying "big hit button" in their rotation?

I know thats a pretty vague question, but I'm a pretty casual new player and I've been playing windwalker monk, which is all about chaining a bunch of skills together to generate my DPS. In general, in games I love characters/classes that have a "colossal damage" skill.I don't necessarily mean a massive damage big cooldown, but rather something as part of their rotation that would fit that description. I'm not SURE something like that exists, but just wanted to see what y'all thoguht.
