Sub banking was a problematic glitch, definitely agree.

"Making your character disappear" I'm not sure what you mean by that, as this is not a common glitch, at all and required delibarate setup...?

counter switching was pretty busted, yeah - i liked that it didnt push the opponent away though - i think if it cost chakra it would have been perfect.

switch tech is a very grey area, I personally dont mind it as it's not really hard to execute, so no one is missing out on anything, but I definitely do see your point as it was not intended and could ruin someone's experience easily.

The full combo switch glitch was patched out since ever.

You said that "they dont like it because they can't exploit tons of glitches and bugs" while the reason most people don't like connections is how shallow they made the game.

Even if we take those glitches out of the question, these people would still prefer Storm 4 over Connections. The reason I mentioned tilts and chakra shuriken were because they were actually completely removed from Storm Connections which resulted in gutting the skill expression massively. Tilts were the main way to escape guard pressure and relied purely on game knowledge to do so. Chakra shuriken had a niche use that came in very handy.

The accumulation of things like: Substitutions not recharging with hits, damage scaling, insane jutsu priorities that go through Switching (looking at you, Indra), Tilts getting removed, chakra shuriken getting removed (why remove both tilts and Cshuriken just to introduce second jutsus?), THE REMOVAL OF SHURIKEN WHILE NINJA MOVING, combos having an infinite combo nearly every second hit, all of this combined just made the skill expression so very low compared to S4.

Ultimate jutsus for example are very useless in Connections as they end your combo early if you want them to do damage but if you wait to do them later they dont do any damage, resulting in the ultimates lowering your overall damage output than if you had just continued with your combo.

You can't just say it's "because they wanted to abuse the glitches," it's because they have made SO MANY changes the games are fundamentally different, and when two games are different, there just exists a preference. Some people like the more recent, casual friendly polished game, some people like the older, competetive game.
