I, for one, am not opposed to more options, I just want those options to be concise and tightened up. Look at 3E; so many of the extra classes after the PHB could have been subclasses if its class system allowed for that level of customization. It's not less options, because I'm giddy to get new and better subclasses. I want classes to be big things. Initially, I didn't like the idea of the Artificer, but some explanations here helped me to see that it was a character archetype that wasn't quite served by what we have.
As of right now, I just feel like the Fighter could be improved by the inclusion of the Warlord archetype. Without the Warlord being part of the Fighter, the Fighter feels like it also holds an "NPC Class" within it (I know 5E doesn't have NPC classes; I miss them).
The lead from the rear, lazylord, and noble type Warlords are the crux that makes me think the Warlord might need to be it's own class. Those character types are fun, and the Rogue and Fighter both have too many class abilities that wouldn't really suit them.
