It's like I said before they need to let mch branch off to musketeer (would be similar to sch/smn). Or make mch the class and musketeer the job.....
We all wanted a gun only job

Even Yoshida admitted that we don't like cyberpunk style classes in Final Fantasy. They probably realized this when mch was the least popular class of all.

So yeah I hope in 5.0 mch gets turned into class that evolves to Musketeer. This wouldn't be hard to do and we all love limsa lominsa, so why not?
Till sea swallows all!
