Ignoring what "OP spells" each class has aside (we could argue for days about warriors and sins and who has the better "spells")
Myself and many other sins tested THOROUGHLY about just how much agility you need to stop a warrior without ANY accuracy hitting you. You need roughly 1.8x their acc as agility in order for you to dodge 2 in 3 attacks.
This seems OP, but the problem is for every 1 acc you gain we need to almost get 2 agility to beat it. Meaning that if you were to wear Acc3 helmet, Acc5 bracers, Acc3 belt and Acc3 necklace. You'd have a grand total of ACC 36. Lets say you only manage to get Acc30 on a warrior, as that seems a more realistic target right?
We would need 54 agility in order to be able to dodge like how we would if you had no accuracy. That isn't even possible to get on an assassin. In fact, the highest possible agility for an assassin (with agil necklace on) is 47, sacrificing everything for agility.
Our spell that gives +8 Agility is essentially completely negated if you were to equip one Acc+4 sharp bracelet... hence why Depress has no problem mowing sins down because he carries one in his bag at all times and already has very decent accuracy on his gear. The more accuracy you get it the worse the situation becomes if you're playing an assassin. You need to start sacrificing more and more dc, and because we don't have a spell that gives DC, sure we can't be hit but we'll just be hitting like a wet noodle in comparison to you.
This is why I'm telling you that no matter what happens, in endgame to endgame kits, warriors still scale far better and will always out match an assassin in RAW stats/strength. Obviously skill of each player comes into play and a lot of other outside factors count in Mir, but in 1v1, that's just how it goes for an assassin.
Sadly it gets worse for assassins because even if you put that much effort into stacking agility, you've just negated one class out of the two that can 1shot you. You'll be running around with 47 agility with something like 70dc and any wizard who see's you will lick their lips and cash in on the free paycheque as you drop in one hit.
