Lets discuss class synergy Gwos.
Some are pretty good.
Like every class benefit from having passives from Knight class, it make them more tanky and reliable.
Mage<>Priest dual caster are great as both class benefit from having other class spells and both benefit from similar set of stats.
Same goes for martial classes like Fighter<>Knight or Fighter<>Rogue or Rogue<>Knight. Passives and active skills either make them more tanky or more deadly. Quite simple.
Priest as support class is also useful as it have some nice passives and everyone in team benefit from extra buff, remove debuff or healing spells.
Mage is kind of outlier in this regard outside dual caster combo. As Mage specialize in offensive and debuff spells - martial classes benefit little to none as they rely on different stats. I guess occasional Cortu may be nice in some fights, maybe some debuff against low res enemies. Well, Rogue<>Mage have some synergy even if not much.
Any though fellow Gwos?
