For real now.

1. Racing+ does make game easier. No one really can argue with this. Having D6 for all chars, having some "broken" deals fixed - when you will have 0% chance cos boss layout is broken in vanilla, having somewhat better devil/angel deals. All these things make game easier BUT you're missing a point WHY it's like that. Almost all of these changes were made to either speed up a game or to make speedruns/races more consistent + more fun as well. Like, for example, curses make game a bit more difficult but in seeded race it will be just a dumb luck if someone will go the wrong way or right way with curse of the lost. So in the end almost every change is justified within a community that you're not a part of that's why you can't understand why Racing+ made this way.
2. "The keeper starting with greeds gullet 50 coins and duality is insane" it's only for 2 custom challenges within a mod (s1 9 chars and s1 14 chars). Keeper got this buff cos it's extremely unfun to play as a Keeper in a speedrun.
3. Schoolbag is not available for every character = it differs between Racing+ seasons/race modes.
4. "This is just like using a seeded run as far as I’m concerned and shouldn’t even be a leaderboard just for fun within a different community" do you really think you can say that when this whole category were made by the speedrun/racing community and everyone is happy with it all this time? There's a reason why Racing+ is a main category now. You can see for yourself how many people do "vanilla" runs and how many people keep doing Racing+ runs and upload new runs every day. People decide what they want or don't want to play. Vanilla AB+ is EXTREMELY unfun to race/speedrun (for majority of people) that's why almost no one doing vanilla runs for like years now. Racing+ is more fun to speedrun than vanilla so this is why Racing+ is the main mod for the whole speedrun/racing community of Isaac for almost 4 years now.

Attacking a whole community that you're not even a part of is not very nice especially when you don't even know what you're talking about and only know that vanilla is "harder".

Don't remember having these issues only with 800x600 resolution or something but might as well just use Widescreen fix and it won't be a problem at all.

I don't think many people would participate, I only thought about making original 10 challenges category speedrun since I really don't see a reason for single-challenge category tbh but this one will be pretty long I guess

You dont need to unlock anything, you can just replace your savefiles with savefiles from the resources page. Simple as that

Because it will be another dead category

Maggy. Shadow doesn't matter on any character, its just an item - you just need to start/complete the run as all 7 characters in the game.

9 char is fine I think

This mod is alright but its not speedrun friendly at all

because greed mode sucks

I agree. it's meaningless

but co op baby is not even a glitch though
