There's no really good way to pick up kinetic resistance that scales at a reasonable rate besides the feat, meanwhile thermal capacitors and electric capacitors can cover heat/cold and electric.
No. It doesn't say 'this feat can be taken multiple times, choose a new resistance each time.' It would be an automatic choice for many levels if it was.
