You do see it in other threads. I get into arguments all the time about not adding more classes or other material, and I've used a few actual examples in this thread (for example, Capn Zapp was so incensed about people disagreeing with him about the premise of adding magic item shoppes and prices in various threads that he advocated for the inclusion of "+" threads). I can't tell you how many times I've had to defend my design aesthetic with analogies (less is more, negative space, leaving space for DIY, etc.). It's fine to like more options, and it's fine to like less, and those are both fine preferences in design.
Yet only in these threads (Warlord threads) do I feel like other posters take it to a ... different level. Because, again, it's not really about the Warlord.
In approximately five years, they've added one new class. And that was exceptionally setting specific. I expect that this is the new normal. Which is why we are likely to see a Psion of some kind (Dark Sun et al.) but not a setting-agnostic Warlord.
So, it's not really about the Warlord. It's about edition warring. And all that stuff
@doctorbadwolf said ... not so much. And just as one side is a gatekeeper defending, whatever, D&D tradition or something, the other side is a gatekeeper to advance, whatever, you can't even voice an opinion. Got it. Otherwise you will be shouted down as the usual suspects upvote each other's contradictory opinions (It's not about the edition war, no, it is!).
That's okay. Really. I don't want to be a part of either of y'alls groups.* Because while I generally support people getting what they want,** I'm never a fan of saying that you can't even have an opinion.
*Normally, I'd use the Groucho Marx refrain here- I'd never join a group that would have me as a member. But seriously- this is toxic. I find it funny to joke about disliking things, so I am often genuinely shocked when I see this amount of genuine rage and hate over something silly and trivial. It's a game. A hobby. It's supposed to be fun. I see the exact type of entitlement on both sides of this argument that I see in the usual toxic nerd battles. No, thank you.
**In the end, even if an 5e is ruined (whatever that means), I can play other editions. And I do. Which is why people should be able to discuss hypothetical additions or even subtractions of classes, races, and so on understanding that none of this really matters. If I, or you, walk away from 5e, do you know what that means? Absolutely nothing.
