Who said they wouldn't get stronger until they're in their 30s? That's a ridiculous amount of time; at least 15 years in Ruby's case, as she's only 16.

They will get stronger a lot sooner than that, but branching out into other forms will just make them jacks of all trades and masters of none, and a master of one will be able to overpower them simply through sheer skill in their chosen way of fighting.

Ruby's already a scythe user, which is rare. Then she's got her gun which she uses as a propellant, and pretty much as a shotgun (despite being a sniper rifle). Her semblance allows her to move super fast, and even seems to allow her to turn somewhat intangible now (when she does the rose petal thing). She doesn't need to branch out, she needs to master what she already has, getting faster and stronger and improving her aim with her gun while thinking of new ways to use her semblance.
