Yeah, I am toning that down. I personally think Thunder should be more powerful against shields. Speaking of which, do Pika players prefer it do what Minus thunder does? In terms of power it KOing off the top like Vbrawl is definitely more powerful
Thunder walls offstage are great (but not unavoidable) against a lot of linear recoveries or rather slow horizontal movement (Wolf, Captain Falcon, Ganondorf, Snake, etc.), but don't work as well against those who can stall around them or reflect them (Fox, Falco [Wolf doesn't because I believe his reflector doesn't stall - and even if it does he probably doesn't have the stalling power to stall and get in place to reflect], Jigglypuff, ROB, etc.).
I think it would be awesome if about the bottom 2/3 was a meteor and the top 1/3 had vertical launching power - this would make it rather reliably meteor and rather reliably kill off the top, usually getting whichever half is better (since I sem to always land the top third when going for off the top, though of course not the entire top third launches upward). I do like it launching downward for most of it if this isn't feasible though.
I get the feeling fsmash had its ridiculous shield damage when they took normal fsmash and made it multihit, but didn't touch shield damage - then instead of being a single powerful hit that does like 4 shield damage, you have like 10 that do 4 shield damage and BOOM shield-breaking fsmash (I am making up numbers here, but I think you get the point).
