You didn't tell everybody which characters you use, or if you even use Cage. Cage doesn't have viable crushing blows, an overhead, 50/50s, and his nut punch can't even be considered a stun due to the forced input delay. When the nut punch lands, you have to wait for your opponent, which is completely illogical. F21 and F344 should NOT be high attacks. F4 is too slow to compensate. The only thing I read your post and others is, "I couldn't stop Cage's pressure in the last two games, so I want him to stay low tier."
Meanwhile, you don't seem to have a problem with characters like Geras that have every tool in the book and then some. Please post videos showing how "solid" of a character Cage is.
