Anyway I rather like the Ronin, but I don't like the stance mechanic at all.
Ronins are not a bad class to have; they just get introduced a bit late in the game. They also have the best attack of any class and the worst defense of any class. Landschneckts are more well-rounded than ronins and can do comparable physical damage if you get the right skills.
But absolutely keep your ronin. Again, the only character you should think about temporarily changing out now is your bard with a survivalist. You will definitely need your bard later, but it is good to have both a bard and survivalist in post-game.
What's so bad about Hexers in EO1, anyway? Low success rate on curses? Bad curse selection?
Hexers are bottom tier. They have weak attack, ok speed, good tec, and less than average vitality. Almost all their skills involve some sort of status ailment. Unfortunately, some of the later bosses are immune to status ailments.
Beyond that, dark hunters can do damage and cause status ailments. So, if you want a status-damage dealer, get a dark hunter and not a hexer. Also, you cannot choose hexers as a class until the 5th stratum! That?s 9/10 of the way through the main game. You have to start them at level 5 and build them up to at least level 50 that late in the game.
also, I understand the tec stat increases potency of skills right? Is there a point to giving it to my medic?
No. Unless increasing your tec gets you more skills, NO. Only increase skill points if they promise to get you a skill you need unlocked. Just click on a skill you don?t have (grayed-out skill) for the game to tell you what requirements you need for that skill.
For medics: Concentrate all your efforts on getting Salve II and possibly Caduceus unlocked. Get revive unlocked as well, but only put one point into revive. After you have these skills, only put points into Salve II, Caduceus, or HP UP. Caduceus is a VERY useful and powerful attack.
