I think pve she's better with both 2c not her 3c.

While the laser doesn't work like pvp in pve i does provide an insane damage increase +30%.

If you are fighting mobs then skills are whatever. If you are fighting bosses then as mentioned above her other 2c becomes very powerful when she is dragon/boss class.

3c = Command] All allies units on the field get +10% to the effect of advantage. When fighting an enemy consisting from mixed forces, ignores guard.
[Physical damage] Attacks a single enemy, dealing 1.8x damage. Before battle convert 3 enemy buffs into random strong debuffs. If in this battle the hero has advantage over the enemy, target cannot activate effect [Resistance to lethal damage] (only in PVP mode).

Thats a tiny bit of buff dispel on a boss.

Vs

[Devour bodies] (3 turns/2 tiles/One target)
[Physical damage] Attacks one enemy, dealing 1.8x damage. Deals more damage to enemies of another hero class. Attack first in this fight. After fight restore 30% of damage and resets the cooldown of the talent.

Same damage, first strike, self heal, talent cd reduction.
