Genuinely... with all my heart, I ask you...

So we all know attack rating has increasing returns. 325 does far more damage then 300, respectively 350 is larger then 325 by a lot, and once you get into the 400's, you're really hitting a train wreck of increasing returns then.
Let's face it, buffs are not balanced well. The SL120 level cap makes this a bit less noticable: namely with the fact that it enforces capping at diminishing returns, which caps most buffs at the low 400's in total contributed damage. This only causes us to only scrape the surface of how broken these skills are however.
Crystal Magic Weapon adds 411 AR, which against 300 magic defense is 206 damage, but if it's full potential of 442 AR was permitted it would do closer to 235 damage with each hit.
Sunlight Blade similarily does 406 lightning with our enforced cap: which is against 300 defense about 206 damage, and 432 AR at max value, edging about 228 damage. (Which makes it in every way inferior to CMW, but this is aside the point)
Then we've got Darkmoon Blade, 275 additional damage against 300 magic defense, but if we could get to 99 faith, that's 300 damage.
I rated this against 300's, and this is about as high as our magic defenses ever get unless we make a build specifically designed for high magic or lightning defense.
This is thrown on top of our weapon AR, which often already is 340 or more, and creates a very broken system that rewards dexterity weapons far more then strength.
Throw darkmoon blade on a Falchion and you're set to do upwards of 700 damage a hit, yeah... you could throw it on your demons greataxe and do 1050 damage in a single hit: but that Falchion swings three times as fast, takes less stamina per swing, and now even has the DPS advantage over you. It's not because it's a dex weapon, or because it's a curved sword (The same effect can be achieved with almost all dex weapons, and even most quicker strength ones), it's because buffs are badly implemented.
If buffs were designed to so drastically increase your weapons power, why did they get rid of curse weapon? Curse Weapon is the only buff that "competes" with the doubling/tripling of the AR that DMB and CMW give to dexterity weapons, which just goes to show that either the devs hate strength weapons or they didn't think things through.
