As the subject states… every time Orcs roll a mythic or anything for that matter, it seems to turn out to be mostly trash.
Gargantaur currently: Deal (Magic +15) damage to an enemy, boosted by all allies and enemies killed. (x15). Costs 22 mana.
Traits are: Huge, Impervious, and Dark Fury. The first two are self explanatory whereas Dark Fury give +8 attack/magic when Gargantaur takes damage.
The problem with Gargantaur is that you need enemy (and potentially ally) deaths to be effective. His last trait wants him to take damage, but he doesn’t have any real defense, so he’s squishy, making it not too effective. It also forces him to be paired with Gar’Nok for that 1 true damage.
My suggestion for Gargantaur is a simple one. Replace the Huge and Impervious trait with Stone Skin or similar trait (50% skull damage reduction or similar) and Orc Armor (+5 armor every time takes damage.) That way, he has better synergy with his final trait. He’s a big Orc, he should be able to withstand some damage, right? In any case, that should make his skill better since people will be more inclined to stick him at the front.
Shade of Zorn…
Deal [Magic + 5] damage to an Enemy, boosted by Red Allies and Skulls. If the Enemy dies, summon 2 Fists of Zorn. [4x] Costs 24 mana.
Traits: Stealthy, Undying, Zorn’s Fury.
The first two traits are self explanatory, but the final trait gives Shade of Zorn 4 mana every time he takes damage… but wait… he’s stealthy, so uh… that doesn’t synergize well. He’s a Mythic, for goodness sake, and obviously this means he’s kinda stuck to being paired up with Gar’Nok again, much like Gargantaur. And on top of that, his skill kinda sucks, as it requires you to actually kill the enemy to get a Fist of Zorn to summon.
Suggestion: Replace the Stealthy trait with Spell Block or Spell Armor (25-50% spell reduction). Change his skill to summon 1 empowered Fist of Zorn, regardless whether the enemy is killed or not. This should help synergize with his final trait and make him a sorta better Mythic.
Just my two cents.
