[MENTION=22779]Hussar[/MENTION] when I read your post I sympathize with your frustration. The people who derail warlord threads don't know how to communicate properly. Sometimes I'm that guy. Sometimes I'm guilty of exactly that.
But when I read your post, I feel that you are being guilty of that too. Rather than try to communicate with people, you're suggesting a one-week ban? wtf? If we simply banned everyone we had trouble communicating with, we could all go back to living in caves.
I believe game rules exist to translate the ideas in our heads -- our imaginations -- the "story" -- into consistent agreed-upon game play. So if you have an idea for a character who is a "warlord" there are three ways to model this character:
1. Using existing rules. (E.g., battlemaster fighter + inspiring leader; it's not too far off.)
2. Using a new fighter subclass. (E.g. PDK, except I think PDK is sucky and just plain weak. But certainly you could envision a fighter subclass that was balanced with the battlemaster but more warlordish. Heck, a few more warlordish battlemaster maneuvers might actually do the trick.)
3. Using a whole new class.
When people argue against number 3 (a whole new class)
they are really arguing for numbers 1 or 2.
Engage them! Figure out what character concept they are trying to model, and why options 1 or 2 work for them.
Maybe they are modelling a character very different than what you have in mind for the warlord? or maybe they've discovered that you can get most of the way there without a whole new class? That could inform your warlord design. Or maybe your warlord suggestion doesn't go far enough? (For my part, I'd only want to see a warlord class if it was radically different than existing 5E classes, not just "more of the same. E.g., if every warlord had troops under their command, that would be an interesting and different gameplay experience. A "martial cleric" like in 4E sounds boring as

Class bloat is a real thing -- it's a real problem, at least for some people. Even if you don't mind class bloat (some people LOVE having more more more), it's disrespectful to just dismiss people who feel otherwise. Don't dismiss them, engage them!
