I have noticed this skill failing to heal for correct amounts. It is one of the more desirable and useful skills for archers considering it is our ONLY method of healing. If we choose to double skill or not, we are more than likely going to have this skill in our main build, or at the very least in alt build.
Another issue regarding Archer skills I found to be strange was the fact that our "Lunatic Fire" Aoe skill costs an insane 45 rage to cast. Now consider this ;
Mage Aoe 's
1 -->(16 Rage) Rain Of Fire lv 5 = 140% M.Dam to all enemies + 25% QTE 10 Sec Cooldown
2 -->(30 Rage) Meteoric Storm lv 3 = +136% M.Dam to ALL enemies + 25% QTE 15 second cooldown.
Each AOE hits ALL enemies multiple times, Deals Magic Damage (which both Knight and Archer are substantially weaker to), and EITHER skill can be cast 1st turn at the start of battle.
Now take a look at an Archer's "Lunatic Fire" AOE skill ;
(45 Rage) Lunatic Fire lv 3 = 104% damage to all enemies, +10% Crit Rate. 20 Second cooldown, +25% QTE.
An archer cannot cast this aoe right away, even if we stacked crit, it would take us 2 turns minimum to be able to fire this far weaker AOE skill compared to a mage's second skill, which can be cast instantly.
When you look at the big picture, this is one of the most broken class skills in the game, for a few reasons.
1. A group of 3 decently geared mages can crank out more far more dps to a group of equally geared archers/knights. This is made painfully clear in Arena/Group Arena and even more in Battlegrounds. The ability to take down troops 1st or 2nd turn as well as damaging the main character creates a huge advantage to AOE mages.
I am a pretty well geared archer, and I find myself struggling against even lesser geared mages.
Im not saying I want mages to be nerfed into the ground, and I'm not saying their build is over powered, what I am saying is that the skills of the other classes seem to be lacking in terms of balance. I personally feel bottlenecked by the limited functionality of archer skills. The rage consumption of archer skills just feels too high for me to be able to use them efficiently.
You can ignore it, debate it, the fact is that there is an imbalance between the 3 classes right now, and if I had the chance to switch, I'd join team Mage without a second thought.
