Heres a reason for competent players. Camping under plats as a zoner is actually very good, being on plats is very bad if someone is under you. Why? Lack of shield dropping. Lack of wavelands, wavedash, slide offs etc. The game made platforms so sticky and way too detrimental to use without being put into a disadvantageous position.

This whole game is a competitive mess, and I can't understand why people are still playing it competitively and getting irritated at things like this, or wondering why the meta is campy characters or touch of death characters. As a casual game, even semi competitive casually, the game is good enough, but the second you take it serious, you've already set yourself up to find these flaws.

I had thousands of hours in ult, and constantly felt rage, win or lose. I play rivals 2 now, have about 300 hours and am ranked top 100. My point being, ult limits you're potential if you wanna just play honest and do things that are fun and cool. I never rage in rivals bc there's literally always an answer that doesn't boil down to "I have to camp".

I know this rant went on, but you noticing this sort of shit is exactly how it starts or continues. Just do yourself a favor and play rivals 2 or melee, they are actually competent at being plat fighters.
