@Kafka, My problem with this mythic is short of there being massive ninja buffs to shade, the devs are overvaluing his usefullness. Much like Phoenicia, it is a troop that does not work with its kingdom or typing and is almost counter intuitive.
As an example, Phoenicia, while having the potential to do high damage, can only do so with Infernus and/or the sunspear hero, who have way better support options. The traits are weak and the spell can do high damage, but nothing so stellar it is a must have and is so bad for her own kingdom that at least fallen valdis does something better in both kingdom synergy and usefulness in general.
As @Shimrra said, the summons are useless for the mythic. On top of that, the spell damage is low with a damage cap that would prevent OHKOs. The base damage can barely exceed 30 with all relevant buffs and the boost sounds nice, except the ally portion is bad as Queen Titania also gets the same boost of 4x per ally AND enemy in an AOE that if there are plenty of red gems, she may not do more damage, but does get an extra turn. The red gem bonus is generally bad as most troops with good boosts tend to remove or destroy the gems for the boost. Leaving them there is risky if one is attempting to get any damage.
Now let’s hit the skull aspect shall we? A troop with zero skull damage prevention, barrier, and not even orc armor? The mythic trait is so bad, I legitimately think you guys have lost all creativity in balance. Aside from the tentacle elephant in the room, Psion, 4 mana is nothing. By the time he would fill up, he’d be dead, well, again. Let’s not forget war, the mythic tank who used to be quite the terror (Give us back pyromania for infernal armor). Aside from war, we have numerous lower rarity troops like crimson arrow, who has agile ad well as eagle eye.
You made a troop that fills zero roles and would be laughable as a legendary with a 14 mana spell. Xathenos does what this guy does, but better. He steals life, magic, buffs his troop type, and can summon USEFUL troops. Instead of giving some buffs to legendaries or mythics who need it, you make essentially a spiritual successor that is even worse. I don’t understand how you can make a legendary that does so much that is useable despite the jumbled synergy, and a mythic that is such a bad orc, I am convinced the reason Grosh-Nak doesn’t have a hero class is out of pure shame.
TLDR: We don’t move Gargantuar from the bottom of uesless mythics, by displacing him with another bad orc one.
