I was playing until now, just redoing all of East to test in scenarios I've been through before to be able to properly compare them. Even found a few more secrets while doing it!
I hate how good this game is, even these changes that I completely disagree with can't make me not love playing it. This is seriously one of the best things I've played in a long time.
I have to admit, there is some fun to be had abusing the dash i-frames, and the dash guard can still be useful because it replenishes your ammo. But even then, you can still just see how the game was completely balanced around the mechanics we had before, and how it's wasted with something so powerful. You can tell you're about to enter an encounter with Ninja Frogs simply because of the conveniently placed cover, made so people who can't deflect or absorb projectiles can still find a way to stay safe other than just dodging, so they can take cover, wait for the shuriken, dash in and attack, but now I didn't see the point. Just go in. Your dash will protect you, and more importantly, health is no longer an issue. It really encourages you to be much more reckless, while the previous version was all about caution, treating encounters as puzzles and understanding the mechanics.
The way I instinctly started to play more and more aggressive reminded me of Bloodborne compared to Dark Souls, but while Bloodborne made you more aggressive with regain, it came with a downside: If you don't control yourself and just go in like a madman, you will get killed. Here, you can just keep going in, healing and you'll be fine, there will be plenty of health for you to pick up, and if there isn't, you can just go back to the warp point to get three (or more) health packs, and enemies won't respawn.
I
think they can still make it work without changing too much about enemy placement and behavior, I'll repeat my opinion that warp points replenishing your stuff can work perfectly fine, as long as that's all you get (or at least less health pickups than now), and "resting" at a warp point or warping absolutely must respawn every single enemy. If they do that, I'm ok with the health related changes.
The i-frames would still be unnecessary, but I think I can deal with that, just because this change could actually make the game harder for people who were already struggling enough to ask for more health pickups, so it's ok, I can do it. Though I wonder if it wouldn't break boss fights. The only one I did was already on my first try having to actually physically dodge their projectiles, imagine if I could just dash through them and hit the boss.
One thing they can do to make it less punishing that I wouldn't complain at all and would not ask for anything to compensate would be to make you invincible for a moment after you get hit. This hasn't been a problem to me at all, but that's exactly why I can't see a reason why they shouldn't add it to help people complaining about this situation.
EDIT: The i-frames also probably decrease the usefulness of multi-dashing for combat. Didn't run into too many situations where it was useful, but I can definitely see some uses for "dash out of harm's way, cancel into another dash to punish your enemy on their recovery", but with i-frames you just dash through the attack and stay in.
This is all very disappointing. I thought the challenge was right on before and made me appreciate the combat a ton. Maybe there's a toggle, but it makes me sad new players won't understand what I thought took this game from good to great.
There's already a "Dash style" toggle on the menu, but you can't select anything yet. So they're definitely implementing it, we'll see which one will be default.
