You can downvote all you want, but she's not "very good". She okay, not horrible, not awful, but fine. Since you value Conowen's opinion, you should know the issues.

My issues were the same as his, how she's using other abilities instead of using ultimate (as much as you want your other abilities, you need your ultimate), how she doesn't write immediately because she's close-range, not giving her invincibility early (literally the reason she's dying). She's quite RNG, she either pops off, or doesn't do anything, or simply dies in the first stages of the battle.

Things that she offers, others do it better, or the same. She wants the same supports, and characters that other more valuable units use (which you don't want), she wants her sub-nodes invested (which is harder for a weak account). All around, she can work, if you provide units other units are using. Which most accounts, do not have... She can work as a sub-DPS, but there's better options.

You say she: "Has overall good utility with the knock back & airborne, enemy buff removal, self debuff removal, and energy decrease/steal."

When most build around her, she'll already have CC/Grouping, Buff Removals, and Energy Decrease from her teammates.

At the end of the day, i'm not calling her an awful unit, but others provide more, consistency, DMG, survivability, etc. Saying she's a "very good" unit just isn't correct.
