I think ledge DI is an important tech, and I think its a marker for someones improvement in the game. DI in general is a tech that is used to separate bad from good and good from great. Ledge DI, in my opinion, shows the growth of a player and takes them to the next skill level. We should be encouraging improvement and promoting advanced techniques. Stages that aren't DL, like BF, take away that tech and what we once had that separated the great from the good is now gone and the we've evened the playing field. An even playing field, in the sense that regardless of skill you can win, is a bad thing. We should be playing on a ruleset that promotes fair and neutral play but can consistently return results where the better, more skilled player wins. If you are not and advocate for DL only ruleset then you might as well not be an advocate for tournament seeding where the top seed plays the bottom seed and it goes in from there. Arguing for other stages is like arguing that the 1 and 2 seeds play each other early so the 7 and 8 seeds have a chance to make it far in bracket (its not fair you're better at ledge DI and better at the game than me and winning, we should play on a different stage that removes all tech so I can beat you with my worse skill and play style).
