RPGs where you have no fixed party members but instead a recruit system

So... I'm a big fan of tactical RPG, and I always hated turn based RPGs.
I wanna give a chance to RPGs by trying to play a RPG but having fixed party members is a big turn off for me.
I hate when the game drops a character in front of you and says ''stick with this dude, this guy is a mage and you better like him''.
That's the reason I don't play most RPGs, even RPGs where you can choose 3 party members between a rooster of 30 is not enough for me. I don't want characters with pre-selected spells, jobs, attributtes and stuff.
What I like about tactical RPGs is that you can recruit totally random characters and put them into your party, so every new game is different. They will always have different attributtes and you can decide what to do with them, choose different jobs and stuff.
