Actually hammer bash, final cutter, and stone has its uses.
Hammer bash is great for reads. If u predict a roll then use hammer bash and it'll get them offstage or kill. It's also a great punish tools. You can punish failed counters, grab whiffs, and moves with good ending lag. Also fully charged it kills at 30% and due to the big shield damage from stone, if you get a shield break then they're ****ed.
Stone is actually good. For characters with recoveries that can't sweetspot the edge like ike, then you can easily abuse stone. It's also a good kill mix-up because it's good to mix up your kill moves. Also on medium shields, it can most likely break it and they'll get a fully charged hammer bash to the face. The fact that it kills at 70% is good and on platformed stages, you can do stuff like dropping through the platform and using stone.
Final cutter is actually decent oos. Also when ur on the edge, U can use it and if they get hit by the meteoring part, you can follow up with fair. U can spike them when they try to recover and get an early stock.
They all have their uses so take advantage of that. Oh and Sakurai said he's not doing any balance updates
