I also think those super pets are good and a must have. I just have few "but" regarding it:
- spawning agent and pet essences drop ratio from lost realms is terrible, i only received few, and funny is that i found them on common enemies, not those devolved. Devo heroes should have much higher drop ratio for it than standard heroes, or add it as second possible reward ,
- spawning agent and pet essences should be available in LR shop and Treasure Trove (didn't saw in any so far),
- amount of spawning agent and pet essences should be also increased from drops. It is already very rare to see them and in combination with small chance of finding it is like Lava Hunting in Labyrinth, really really slow,
- super pet snacks should be available as drop from specific game mode like hero trials, not from spawning. It is annoying to see them instead pet,
All for now, i will edit post later if i will have new suggestions.
