I can't really adress this point by point, but I will tell you this from someone doing analysis of the trailerA lot of people are already thinking he's going to be OP as all heck.
...I honestly did NOT get that impression at all seeing his trailer. He looks cool as hell, don't get me wrong! But crazy powerful is not what I see. I can't play until later today (gotta get through work first...but its slow, so I can just mess around here all day), but I'll just lay my thought process out:
- Eiha is weak. Like....crazy weak from what we saw. Even with its poison-like continual damage, it hit like 10% on that Lucas. (Or was it Ness? I confuse the two..). It may have just grazed him maybe? But it looked like a direct hit that only ended up being 10%. Maybe it could stack; who knows. One thing to know is that it didn't look like it had ANY knock-back at all.
- Gun is very similar to Bayonetta's in that he can use it all over the place (even in dodges; that's epic), but the damage output for it is small as well; it's basically just chip damage with no knock-back (may not even stun or interrupt like Megaman's lemons).
- Grapple Hook is gimmicky; like Samus' tether or the Belmonts' chain grapple, it can be difficult to use. At least for me it can. At least it's a simple up B that you can manipulate the direction for, but depending on how close you have to be when you fire it, it could be difficult to get yourself back to the edge.
- Rebellion Guard is similar to Limit, but you can't charge it yourself. You either have to let it charge on its own (which they said will charge faster if you're behind) or you have to fish for hits. You take half damage while using it, but there's plenty of characters who can abuse this and just rack up your damage with free hits while you try and get a charge. You also lose all charge thus gained if you're KO'ed. That means you'll pretty much always be using Arsene while lagging behind an opponent percentage-wise.
- Not being able to charge this gauge on your own is a lot bigger deal than people seem to be making it.
- Arsene is timed; he won't always be out once you max out the gauge, that means that regardless of your playstyle, you're encouraged to be much more aggressive once Arsene activates. This makes a player pretty predictable and opponents can just play a waiting game while they try to wait out Arsene. Those that can't escape will just fight as normal against a character they've already likely put a fair amount of damage into already.
And the Pros to this? He powers up, but we never actually saw just how much. I'm sure it's a significant amount, but probably not as game-breaking as people are making it out to be. His recovery becomes one of (if not the) best, that's for sure, but the other moves just get stronger as you'd expect and there's still no knock-back (Eihagon took up like the entire character screen, so I couldn't see if the opponent was stunned or not).
Basically, he's going to actually be somehwat similar to Lucario, if that makes sense. A little weaker than average at the start of a fight, but once he accumulates damage, he becomes a force to be reckoned with; a Revenge-Killer if you will. Of course, it's temporary though. I think that's the biggest thing holding Joker back from being the OP force a lot of people are initially believing him to be.
Unfortunately, I can't test my hypothesis on the matter out until later. Hopefully someone here can take a look. We need an unbiased look at just how good he actually is lol.
-Guns cause hitstun up close.
-Arsene basically gives him Fox Usmash. It comes our real quick thanks to Arsene frames coming out sooner.
-Arsene has a timer but it is really long. About 15-25ish. More than enough time to play neutral.
-Arsene grants a speed buff.
-Eiha is inocuous, but becomes active pretty fast
