Why do you assume they weren’t given the chance to change?
And you preset it in the class or character customisation tab, depending on what you’re changing.
It’s actually just disrespectful to join someone’s lobby or game and not follow their rules.
And what if you intend to join the lobby and change your setup to suit it?
Of course if they don’t change you can throw them but you at least need to give them a little bit of time to do so, not immediately hit the trigger finger after only 5 seconds which is NOT enough time do do so.
And you can’t change characters for PvE outside of a lobby afaik. Which would be time consuming and the free slot might be gone by then.
I did give them time. I said that, after a few minutes nothing changed.
I’m not that mean.
Well that’s an awful take, it’s asinine to join a lobby if you think the rules are “silly”.
My question was of general reach, not just in the one particular case you mentioned. Also don’t see where you mentioned that you gavw them several minutes to change in the lobby or if they joined mid-match.
Ha, brain fart.
Thought I had, I’ve not been up long. It was in the lobby, we were watching and waiting to see if they’d change for a bit, nothing happened.
Sorry.
If something discourages me from joining I just move on, especially since a lot of people don’t read what is said anyway. Which is what this thread’s about.
That aside, I like variety in the game.
Some of the rules I’ve seen are silly, yes. Maybe not yours but I’ve seen worse.
There are worse, I just enjoy the voice lines on Gears and like to hear as many characters speaking as possible. Personal taste, which is why I put it on my lobby, people may or may not disagree.
On the opposite side, sometimes people don’t read their own rules/change them for a new match;
“Master speed run! 1-50. 18+” and its frenzy on insane, they’re already on wave 4.
And there’s some that say “deposit all”, then halfway through Frenzy, they go like, “perk”.
Or if they have banned a certain class and when I join, they may be like, “you’re alright, you can stay” and they start…
“Kait, Paduk, Keegan”, but when joining as different character, they just start anyway…
Yeah, it can get a bit confusing!
Fortunately my “rule” is so general I don’t have to change it.
Do they mean the skin or their old class?!
Inquiring minds must know!
Though it’d be nice if you could lock slots to specific classes/roles.
Like slot 2 could be Combat Medic/Jack
Slot 3 Infiltrator/Blade master and so on.
Would help a few people cater to their desired incoming players.
It was in Op 4 when I would join Clock runs. I had played with the host before and they were pretty good. But unfortunately, they listed specific characters that weren’t not necessary. So I’m guessing when I joined, they didn’t mind which character I played and started anyway.
You could say I didn’t read the lobby title. 
Well I did, but sometimes hosts give you a free pass.
MONSTER!
I think there is a large issue of people not checking what theirs says at the moment though.
I might change mine to no WWE characters…
Be nice to all the noobs out there…
Had a host that kept on saying “Mac vklad” on the chat only for Mac to reply back with “???” and the next thing you know he got kicked out of the game. I did google translation and the host was saying “Mac deposit” in Czech 
You mean you don’t understand the MIGHTY CZECH language? How uneducated are you?! 
Nope
Their lobby, their rules. Let 'em enjoy the game how they want to and find a different lobby. Or better yet, make one. That’s been my philosophy.
Plus I agree with @Watery_shoe, it’s a much better horde experience when everyone plays different classes and characters. When there are duplicate characters it’s so much harder to keep track of who is who and what super is popping when. A character change shouldn’t be that hard. We can pick (almost) literally anyone we want.
Level 19+? A little crazy don’t you think?
Their lobby, their rules. 
Though for most classes, getting to lvl.16 gets you all the cards you need, and the daily and weekly challenges in Horde and Escape get you tons of cards quick, so I agree, 19 is kind of really unnecessary.
Yeah I know.
Just voicing my thoughts. I will just make sure not to join that lobby.
I used to have Master set at Lv. 16+.
Now with Operation 5, some classes have skill cards that unlocks at level 19. I want to make sure they have every skill card at their disposal.
And if RNJesus is on your side, you’d have enough duplicates of your other skill cards to get them up to Lv 5 or 6 by Lv 19.
Okay, someone doesn’t want to put some effort into it…
