Buff Arrow Shield?

I've been trying to use this ability at its max lvl (Lv 67 here) and I have found it to be a strictly worse version of bomb arrow. The damage is weak, it only has 1 use, takes up a lot of mana, and doesn't knock them very far back. The level 3 version is completely useless, seeing as it only works outdoors and even then it does nothing. Just my suggestion for different scalings:

Lv 1: Arrow Shield - Same as it is now, but with 3 times as many arrows surrounding you for aesthetics. Still dissipates after 1 hit.

Lv 2: Arrow Burst - Rather than shooting the arrows in an upward arc, when the shield is hit it shoots the arrows in a horizontal angle bursting from you. This would be useful anywhere and would be more powerful with the x3 arrows.

Lv 3: Arrow Blast - Now disappears after 2 shield hits and deals more damage. The same enemy can not be hit twice within 2 seconds. It despawns at the normal timing. 2 bursts of arrows can be shot this way.

Just another suggestion, comment so I can improve.

 

In my opinion arrow shield is fine as it is. It already knocks back mobs that would otherwise tear away the archers' health due to its low defense, and it already has very powerful spells like Bomb Arrow and Arrow Storm if used correctly. Don't forget that Arrow Shield gives blindness, which immobilizes MOBS, preventing them from dealing any sort of damage to you unless they are casting a spell. However, I will partially agree that Grade III Arrow Shield needs a little small tweaks, being that those arrows move horizontally from the user when activated, instead of upward, but the amount of arrows in the arrow shield itself should stay the same.

 

Archer is actually very Overpowered as it is, Arrowshield isn't meant to deal damage, it's meant to keep players or mobs away from you

 

The problem is that escape also gives blindness at lv 3, does more damage, and has the same aoe. I find the kb to only be about 5 blocks, being rather useless. And I know the other two are powerful but shield is just flat-out useless, especially for the mana cost. Even with it you have to have a high-evasion build because you can never have enough mana for it. That's why I proposed the 2-hit and horizontal arrows. Thank you for your opinion, some of your points I do agree with.
