For someone claiming I can't read, you sure misread the entire point of my post. No the changes to Batman and BA wouldn't be bad. As I said, they would actually stay ridiculous because they have safe blockstrings.
However, some characters use their specials to make themselves safe. Take Green Lantern for example. With that in play he has literally no safe strings (Well, no useful ones. IDK if some of the ones nobody uses might be safe).
Doomsday is another example. With these changes you might as well remove his venom charge from the game if it's going to be negative on block. With that in play Doomsday now has very few options to get close to his opponent (Yeah he has trait, but multihit moves blow that up so hard, as well as a lot of characters with fast D1s) and venom charge as a move no longer has any point.
Oh and speaking of big characters with armor... How do you want this system to work for Bane? Every time he uses his trait it costs a bar of meter? All of his moves are now unsafe on block? What is the point in his existence then?
Oh and armor costs meter? Congrats, Grundy lost all of his reset potential. He doesn't build enough bar to compensate for all walking corpses costing meter.
I could keep going, but the point is that your idea would nerf the hell out of some characters (Mostly the mid tiers) while barely touching others (most of which are already amongst the better characters in the game).
By the way, I am a Joker player, so you know, I'm already playing a character considered to be garbage. Your idea would make characters like Bane and Grundy 1000 times worse than what Joker currently is.
Here we go....
To start, Joker isn't garbage when you have the resets that he is capable of and the corner game he has when he touches you. He isn't the strongest zoner but he can keep majority out, not like MMH or AM, but he can hold his own; and there's pushblock. He is reminiscent of Cyrax in that sense where once they touch you, it makes up for the damage they've been missing out on and eventually even more.
As for specials as a whole, I'll repeat, I said up close and I said meterless. Moves already like flying uppercut, corps charge, lasso spin and things of the sort. Doesn't need to be -15 to be deemed punishable/unsafe; several -7 moves on block that DO get punished if the player knows the MU. Silly moves like ice breath, lightning cage, mace charge, black ice, etc. that have so much pushback AND/or are safe if not advantage is again, obnoxious. If it's going to have that much pushback, (purely my thought here) it should be where you wouldn't get punished but you can't backdash out from fast follow ups.
When it comes to armor, tbh I'm just gonna say tough. There shouldn't be a go to free armor setup that can't be dealt with by pretty much everyone. Sounds like a braindead point of view to say meterless armor is a must -____- Really now, all this does is make you think twice before just moving in not giving a care in the world simply because you can, but instead makes you lay out your play and adapt to different scenarios. Speaking of which, if interactibles are such a must so you feel good enough to say it's something 'new' (which it isn't), they should be blockable for 5% chip. Is that fair enough or is that going too far for currently unblockable, tracking damage?
Doomsday's venom charge ***meterless*** already is unsafe the way it should be. You gain advantage spending meter, as it should be, which is exactly what I said, now it being two times. And to wind back to Bane and Grundy, you still have your grabs, Grundy still has a huge damage output, they could buff Bane's damage a bit if he'd no longer have trait, but they can still set you up. Like Aquaman, you'd now only have to pay for your mistakes now. My sincerest apologies that owning up to these mistakes is such a bad thing -__- And I'll repeat it AGAIN, characters that rely on trait as their move set like GA and Ares should just have these specific moves turned to specials. They can buff the speed and change the properties to being lows and overheads so you'd have a good mix up game if you make the right reads.
The point is, think before you leap. Don't expect there to be a soft landing all the time. That's what this is all about
