I'll be blunt. The proposed ruleset is terrible. I get you want to get more people into running this game, but there are way too many arbitrary restrictions that simply cannot be enforced without a lot of headaches. And very idea of making a new ladder just for beginners WITH serperate rules sounds fairly selfish and unnecessary to me. If the glitchless category just restricted any momenteum throttle techniques and side attacks, I still would have second thoughts, but it sounds much more legitimate (I'd argue MT shouldn't be restricted, but I'll leave that issue alone on this post). I have issues with the most of the second half of the ruleset. I'll go through them one by one
-No shift boosts... but hidden ones are
There will be players who won't join this ladder just because of this. Some new players do try to learn the advanced techniques, especially shift boosting. Both types of shift boost requires precision and a certain level of execution. And what if a player accidentally goes off the course for a moment and comes back with getting a shift boost. That has and will happen to me and other players on SOLS, CPDB, CTT, FFU and any course that has any part that has no walls.
-No broken down finishes
Again, a pain in the butt to enforce. And this sort of thing doesn't require any special inputs or techniques, just hitting the wall right before you finish. Without MTSing, it really only saves a significant amount of time in Ordeal, which is fairly easy to do anyways. And again, especially with newer players, they can do a broken down finish by accident, which most of the time would cost their run time instead of saving time. Would you disqualify a run just because of that? Oh but you'll make an exception then? Rules in this environment can't have exceptions.
-No AX parts
Honestly it's a valid rule, but why bother? The advantages of the maximum star is negligable at lower levels of play. None of the AX body parts are OP. If players are most comfortable with any of the AX parts, then they should be allowed to set the best times they can get.
-Quick turning allowed except...
Stop right there. The moment any rule in a speedrun ladder has the word "except" is a bad rule. In my opinion, machines that can snake and cut time with it at 100% is perfectly okay with me. I consider it just one as one of the advantages for a machine to gain speed in corners and perhaps benefit from snaking at 100%. Does this mean machines like Big Fang, Hyper Speeder and Wild Boar won't be allowed to quick turn because those machine gain speed when doing so? Oh but those machines can't maintain a higher than normal snaking speed in straights. You see, nailing the specifics of this rule is a huge mess, and the idea of banning techniques from certain machines makes no sense at all. What I'd do is not have this rule at all. If someone is suspected that someone snaked at 100%, then ask for video proof of the run.
I am not at all opposed for you to try this informally. Have a topic here where you can discuss and submit times by posting. A few people would be allowed to update a spreadsheet and post the total times and "records" in the opening post. However, I wonder how you and others would feel if players like myself decide to try this out. But this should never be an official F-Zero GX category.
