I had to reawaken from my slumber just for your comment…
Let me be the first to say… No!
First of all Swordsmen don’t have an advantage in managing their HP. Technically clerics still have that advantage over every other class by far. Swordsman’s HP was mainly designed in consideration of them having to face tank 90% of the time they want to deal damage.They don’t have a Safety Zone or healing type of skills, nor do they have any form of invincibility unless you count Reitarius’ “Vital Protection:Near Escape” attribute, and even then you’re on the edge of dying. Unaided by anyone else, Swordsmen use HP potions and have higher hp pools, that’s all they get.
Second, almost every swordsman has to consider block penetration and/or accuracy since they are physical damage dealers. Most Clerics won’t have to worry about that… ever.
Then we have to look at how magic circles work. The beauty of magic circles is that in most cases you can set it and forget it most of the time. Not much face tanking required when it comes to magic circles. Literally every cleric build will have some sort of magic circle skill in their kit. To combat how easy magic circles are, the Devs thought of adding a magic circle breaking mechanic to certain bosses, a “band-aid” type of deal imo.
You mentioned Lancers… Have you seen what lancers have to work with in their kit!? They don’t wear shields, they have no real defensive capabilities. Their skill hitbox ranges are small, the ones that aren’t small do small damage. They are pretty much designed to deal big burst damage every 20 seconds or so with everything else at the cusp of being borderline useless 70% of the time, when compared to what most Clerics have in their arsenal.
Swordsmen and Archers for the most part don’t have any skills that scale on SPR. Clerics have quite a few.
So do we really want to give the face tanking, low defense, short ranged, burst damage every 20 seconds, no support skill class more burdens in the form of higher SP? I don’t think so.
Where are you even getting these SP cost amounts anyway? Wouldn’t the Acrobatic Mount buff from Cataphract + the cost of using Crush + the cost of using Quintain be more than 205SP? and that’s not even level 15 yet.
All this to say… you can’t suggest what the SP cost of a skill should be based on what you just mentioned. There are other factors to consider. The Devs are still struggling to find a good balance in all this.
