@Nilrem psh! I want Mana shield to be uncapped to rank 1. Also Mana shield is not impenetrable. You use dance of death and dischord with the right reforges, Hydra, skills like that and you can mess up that tactic. Even with my Mana shield at rank 6 and my Mana shield damage reduction 19, if someone uses a combination of those skills it can wipe me out pretty fast. Also the Duke from peaca can bypass that shield. So yeah it's powerful but not fail proof.
Mirage Missile is amazing, I don't know why everyone is hating on it. If anything I would change the spread AoE and frequency (though not damage frequency, as that would hurt the overall duration).
MM compared with elven movement speed makes you literally untouchable against a single enemy. That's the whole point. It also deals great damage on impact, it's basically a mini magnum that loads much faster and slows. It's a fantastic skill.
I object to all changes you're posing aside from dual daggers, especially the melee skill. Elves aren't supposed to be warriors/lancers, that's clearly anchored into the lore and stats. They may one day have a talent that allows them to be decent in melee, but it should not be warrior or lance combat. I'm saying this as an elf. We're not all mighty.
Also, other people: don't argue that archery is god-tier in KR. While it may be so, we have to keep pushing for an update that will benefit everyone, such as a damage formula for archery that incorporates latency as a variable to adjust the damage based on how much you lag. All these aim speed buffs are meaningless to people who don't live next to the servers, especially us europeans, who don't have an own server anymore.
Hide is fine the way it is.
Hidera is about the only thing you can do with it and its usefulness keeps getting smaller, plus the damage per second is really low on that one and that's fine.
Final Shot needs to activate like way of the gun
EDIT: I forgot while writing this wall of text, but an elf revamp should probably also involve magic. If we ever get an elf revamp, I assume that might also be where it'll go, instead of more archery.
