For me I think it's gotta be Rogues. I generally do vibe with stealth/sniper classes, so there were only a handful in the running for favorite - but my rogue was enough to beat Amalia basically solo at lv 25. Paired with Berengaria, Travis with a pursuit is just a beast - he has AP and PP for days, blinds whole rows, poisons, and sneaking edge is great for getting rid of tanks early. Hit him with magic conferral and he cuts through everything. The only problems are archers and swordmasters, which is unfortunate because there's no stealthy way to deal with them (that I've found) and you need to either focus them early or give him added protection... I do also love the werefoxes and all the archer classes, fencers, and swordmasters.

Witches are excellent.

Bishops are way up there for me too, which is crazy because I always found them to be frustrating to keep leveled and keep up in fights in games like fire emblem. Love that they can just stay with a party now, although don't love that it's kind of annoying to heal another unit sometimes.

What are your favorites?
