I expected a fellow freya berserker user to know better, but saying her aura allows for "1 enemy turn = 3 chances for your units to attack" is far too idealistic. Firstly, the enemy has to focus on your freya berserker for there to be any chances of proc-ing the aura. Assuming that the enemy attacks 1 target randomly, that's a 1-in-5 chance to proc an aura that only has to 30% chance of occurring. It is in fact infinitely worse than what mind warder kiera has and to be perfectly honest, I would be so glad if she had mind warder kiera's aura, which has a 4(3 in aura+herself)-in-5 chance of proc-ing an aura that occurs 40% of the time. So while certain reactionary auras are decent, hers is complete garbage, and it's not just the trigger chance.
Moreover, the stun component is completely useless in PVP. Even if you're lucky enough to get multiple members in her aura to proc it, they 1-turn-stun the same enemy, lmao. As if a 1-turn-stun in PVP isn't useless enough already, they had to go stun the same enemy repeatedly even when he has used his turn to attack freya already.
Overall, freya berserker's aura can only be summarised as a poorly-conceived aura that turned out to be incredibly impractical when put in practice.
I do agree I'm being idealistic, and I already mentioned it is very much RNG and less reliable than a given 75% proc. Of course I know it requires focus on Freya but we know the enemy AI is not as random as 1 in 5 units to proc; they will target based on lowest Def and Hp, so that already eliminates some randomness. In that manner, there are ways to manipulate the AI.
In any case, your thread's focus is on Freya's skills and aura, and I'm just providing feedback based on my usage of her. Let the Devs read and decide.
