Should Nexon bring back Inner Ability Locks?

My bad, i thought they were rips of potential locks which didn't appear in KMS.

I have my suspicions that Nexon of America made potential locks because of inner ability locks, though while inner ability locks appeared first (as in, the first time they ever appeared (in kMS) was before potential locks in gMS), they were probably conceived around the same time.

I like that it holds rank and not the line, though, since more often than not, you'd probably get a crappy line on a good rank, but I, too, would like the option to hold line as well. An S Lock would be pretty nice, but I'd settle for getting some nice crit or boss A lines.
