FFVI - I tend to use everyone a little but I'll admit I usually bench the Figaro Bros in order to make the game more challenging and I probably don't use Gau, Strago, and Gogo as much as I should.

FFVII - Yuffie, Cait Sith and Red XIII are usually the ones playing catch up the most in the game for me.

FFVIII - Selphie and Quistis, their limits are just not as useful.

FFIX - Amarant, Eiko, and Garnet are usually benched when I finally get full control of my team.

FFX - Yuna and Kimarhi, healing is really easy in this game and Rikku's a superior healer anyway and Kimarhi just has not good niche on the team.

FFXIII - As much as I would like to bench certain characters, Sahz unfortunately always tends to get picked last due to losing a lot of his useful qualities once the whole party is available and sadly everyone tends to do his primary Roles better than him or have more useful combinations. It doesn't help that he has my least favorite summon in the group.

FFTactics - Most of the specialty characters that are not Mustadio, Agrias, T.G. Cid, and Beowulf.

FFTactics Advance - Same deal as above, most of the specialty characters are not worth the time except Cid and Ritz. Even then, it's a shame both are relegated to post game nonsense.

FFTactis A2 - Cid keeps falling out of the plot too much and can never play catch up, I also usually drop Adelle because she's annoying and her Inheritor Class is a dumb idea and OP but only really comes into play in the post game.

Persona 1 - Ayase and Brown tend to get shafted unless I'm doing the Snow Queen quest. Ayase just has poor weapons and Persona choices, bad stats and an irritating personality. Atlus seems to agree because she's still the only character from P1 whose fate is completely up in the air as she doesn't get any cameo/mentions in P2 and P3. Brown is equally annoying but at least he's a better party member.

P4 - Chie and Naoto tend to be benched a lot, mainly because they are both too tailored to one type of role with Chie being great for boss battles but terrible in dungeons, especially since melee defense is way more common than I would like in the game, and Naoto is the opposite, being great for dungeon grinding but worthless in boss battles due to her spell repertoire being instant death magic and overly expensive Almighty spells that Naoto's stats can't make any use of.

DDS1 - Cielo just has bad stats, a bad weakness, and is annoying as hell.

Breath of Fire - Pretty much everyone that isn't Ryu, Nina, Dias/Bleu, and Karn. I tried using all of them but they are just not as OP as this team.

Breath of Fire 2 - Jean, Stan, and Spar: Jean has been discussed on the fact he's kind of a lousy character in general, Stan is a bit more useful but he's basically a Red Mage type with troutty defense and his special move makes more vulnerable characters a target. Spar is also a bit mediocre, especially how late you get him. The main thing all three have in common is that all three have some obnoxious story sequence you have to go through and all three of them are infinitely better with the Shaman System in play.

Breath of Fire 3 - Nina and Peco get the short end. Nina is great in the early sections but once the Dragon system starts to expand, she loses her niche on the party as an elemental damage dealer. Peco is pretty much like Kimarhi, he can be built to your specs but the game already gives you great people to fill most roles you may want to give him.

Suikoden I and II - Most characters that are old, young children (10 and below) , and have a non warrior/mage profession. The series plays all these types very seriously especially in S1 where you're often forced to use doctors, farmers, and scientists in battle who can't fight to save their lives.

Mass Effect - Kaiden and Ashley, Kaiden is just a terrible class and Ashley often got benched cause I played Shep as a Commando so she was rarely needed once the full party came together.

Mass Effect 2 - Jacob, Miranda, Grunt, Samara, Legion, and Zaeed. Didn't care for any of them, except Legion but he arrives way too late in the game to really care. Game had way too many characters if you ask me.

Xenosaga - M.O.M.O. and Ziggy for the most part, not bad characters but Ziggy is too slow and has an advantage on very few types and M.O.M.O. is too frail until end game and her niche can be covered by Shion.

Xenosaga Eps.2 - Ziggy and Chaos. Ziggy again just has bad attack types that are useful against very few types that other speedier characters can't cover and chaos got nerfed as all hell in this game and lost most of his type advantages.

Wild Arms 2 - Laika and Marivel, Laika gets supplanted by the more useful Tim once he fully joins thanks to some of the bad balancing for her Crest Magic and Force abilities. Marivel is pretty fun to use but can't pull off the type of damage Ashley, Brad, Kanon, and Tim can do.

Dragon Quest IV - Meena, Borya, and Torneko. The first two just have awkward spell sets that happen to not include my go to spells in the series so they rarely saw action when I had Kyril and Maya as options. Torneko is just a bad class combo and losing his ability to get enemy drop rates more often after his chapter kind of sealed the deal there. I also don't really care for Psaro either.

Dragon Quest V - Pretty much all of the human characters not you wife. The great hero is surprisingly crummy.
