Yeah, nothing bad to Tommen YET...but that's what I'm saying, I think the aging up means something more because in the books there's not much acting required and an older actor couldn't possibly play the cornball role that kid has in the books. I doubt his sister loses her ear too, just gon' be a scar.
I've seen his dialogue in the books so far and it's not complicated...and some of it won't fit with the older actor (crying over kittens or what he has to eat for example). The bad acting thing is true in a lot of cases, but this isn't a really demanding role unless the tv guys have some real changes planned...or there's more to be seen in the later books. So far, he's been an after thought in the books.
