After reading alot here...especially the section where new suggestions for the game are made i think i was wrong in thinking wizards in endgame are best choice. Seems physical damage is superior to magical.
So what you think about this Combo:
(fighter) warfare + summoner
(fighter) warfare + polymorph
(huntsman) ranged + polymorph
(wizard) hydro + geo to support armor and healing
Honestly, I would not bother with the wizard. I played with a somewhat similar build in my first playthrough and the reality of it is that your wizard is dead weight because that occasional heal/buff/debuff is not going to be useful enough to justify the spot of a fourth physical DPS. Also, physical damage characters get enough debuffs from Warfare that the role becomes somewhat redundant. If you are playing on Classic, it does not really matter as you are unlikely to really get stuck anywhere for particularly long. However, if you want a cookie cutter build, do the following:
1. Fighter with Warfare + Dual Wield (2x1H weapons)
2. Fighter with Warfare + 2H (2H weapon)
3. Rogue with Warfare + Scoundrel (2x Daggers)
4. Ranger with Warfare + Huntsman (Bow/Xbow)
Warfare is the bread and butter of every physical build so do not be afraid to skimp on it. If you want more of a "Tank" character, take Leadership on one of the Warriors. With the above party your run should be an absolute breeze.
