I'm not sure how deep the Switch Skill system is but I have to believe there's support for a lot of playstyles, including one that might be more fun for you than what was locked into the demo. Spending more time with the system will help a bit in general too.
Monster controlling, from my perspective, is basically a re-implementation of the MH4+ mounting mechanic, just with some more (ignorable) flexibility in movement. You can "mount" and "finish off" monsters in roughly the same time if you're rushing in both games it feels like. It's definitely not deep enough to be a highlight feature or anything (despite Capcom's marketing), but it is a fairly show-off-y way of scoring big damage 2-3x a hunt.
And Capcom increasingly seems to be pushing the series in a more flashy, actiony, DMC-y direction. Starting with MH4 mounting, then Hunter Arts in Generation, to I assume the Clutch Claw in World... Some of the Wirebug moves feel very "character action game" to me (not to mention, traversal and wall-running.)
