I pretty much universally enjoy support convos in FE games, even the fanservicey -sama ones.
But yeah as stated the central game elements I kind of just ignore... not saying you guys don't have problems with those (support) as well I just kind of feel that's the #1 source of replay value and the thing that drives me in the game as much as anything.
Finally.... VA.... not against VA, not really count... I don't know... I just am neutral about VA. Notoriously bad VA like Evangelion English dub or something I often just find entertaining anyway.
Anyway, to a certain extent I think FE is like the goofball in the Nintendo lineup, it's entertaining but I don't really pit it against Metroid, Zelda, even Mario, to be honest, it's for the hardcore fans of Nintendo who don't mind a sharp SRPG (I honestly enjoy some of them more than FFT, frankly).
As far as just being a blast of sorta silly and fun I thought Fates was great, ditto for Awakening... honestly I kind of feel like the series until it was released in the US seemed like a boring kind of "Mainline Nintendo clone" but since it was trying to cave out this unique medieval/RPG feel it ended up just seeming dry.
Then Blinding Blade and the Radiances kind of established a clear identity, anyway, IMO, where it's more wholly embraced the fan-service and silly sides to create something pretty.. just... fun.
I'd actually say the gameplay has gone slightly backwards, for example the way upgrades were treated and item values, gold sinks, farming, it was getting a bit silly at certain points, but I don't know if for instance, perma-death was worth the tradeoff for those things in other games.
TLDR: FE was a black sheep that morphed into a pretty fun franchise by accepting it's inherent silliness.
