Fire Emblem supports peaked with FE8\FE9, few are stand outs in FE6 and FE7.
After FE9, supports became even worse than before (FE10 is full of generic “how are you”, “let us fight together”, “yes we are comrade”, FE11 has none, FE12 has very few good ones such as Arran’s (very tragic character that was not explored enough), FE13\14\15\16\17 is post 2013 generic anime tropes galore)
There is one very easy solution: toggle-ready voice acting, so that if one played the games already, they can keep having their canon voices play in their mind as they read the characters dialogues.
Well, voice acting can be very cost-effective if high-quality models are used for tertiary characters, for instance, such as “generic soldier #2” and the likes.
