You raise some good points.
What are your opinions on the new shielding mechanics with low stun and replenish fast? To me, this is even worse than the ledge trumping.
I agree that planking / endlessly refreshing invincibility a la m2k is pretty boring and lame.
I don't see why casuals hate edgehogging so much, it was even a point bonus in melee, you were literally rewarded with points for doing an edgehog (I think the game referred to it as edgehogging as well?)
I forget what it is called but I think it was in Melee as a bonus.
Regardless, casuals hate it a lot no matter the game. And to give the newer games credit, they listen intently on big changes the vocal majority want.
They think it is a lame way to die, spike? No problem. Hit hard and died? No problem. Edge hogged? Now you crossed the line.
Then add on planking, not just brawl this is an issue. Jiggly puff plays in Melee, a Canadian one did this at evo last year, abused the ledge to camp out games. Add in Shiek ledge stalling, since she is only vulnerable for 1 frame, and it makes hogging her risky.
I get why they changed if, Metaknights planking was cancer in brawl. It added more incentive to fix it. Now it is harder, but still skillful. Setting up frame traps from a trump, the edgeguarding is still there with an opponent to have some counter play to get back.
There is still skill to doing it, it's just not as free as Melee is when you end up off stage.
I like that shields break easier/get poked more often. There is no more shield damage debuff from Melee and Brawl.
I think shied stun is fine, kinda wish there was a tad more but it's good. What I do like is how smash 4 buffed empty short hops. If you shield and don't get hit, it takes a long time to drop your shield, empty hop>grab or Empty hop>step back>smash. A lot more mind games with it and it has done wonders for me.
Shiekd's replenishing I kinda have a problem with, that is Too fast, but I guess without it projectiles characters would be pretty bad lol.
