I understand that Gobbler is a novelty hero that is supposed to fill an unusual niche. I have mine almost maxed and I began using him on raids and noticed he has an almost fatal flaw in his design. His defense (450) is so low that he is unlikely to survive long enough to use his SS. He is not only the lowest defense among all 4* heroes, he is 57 points below the next squishiest hero (Scarlett). His defense is only really comparable to 3* heroes.
Keeping that in mind, the only heroes that spawn minions, as of this writing, are 5* heroes (Thoth, Delilah & Red Hood). The teams that tend to have these heroes are fairly strong, usually TP 3800+. Given the kind of environment Gobbler faces, how could one expect him to be effective? Granted, his health is higher than the average 4* but I looked up the way damage is calculated. Since damage is computed as a function of (attack / defense), an abnormally low defense will result in much higher damage to Gobbler than a typical 4* hero. High enough such that the 1302 health doesn’t seem to matter in terms of his survival. If his defense and health were aligned like a typical 4* such as Little John or Melandor then Gobbler would be a more playable character. Those two heroes have a similar attack strength as Gobbler but don’t have the survival problem. As it stands now, there’s no way to put Gobbler into a fight against the very heroes he’s meant to counter.
