The community has long ceased to care about the aesthetics of uniqueness and now focuses on the practical impact of certain actions on balance and gameplay.
Chupa, among other things, limits the player in terms of development. For example, when playing with Chupa, everyone only chose Water and Fire – for transportation. Earth, despite its usefulness, was rarely chosen, simply because Chupa was almost guaranteed to be present in the final stages.
When Chupa was banned, suddenly all three elements became useful, and people even started experimenting with Air from time to time. They also started taking various magical skills more often, such as Intelligence, which were previously considered useless with Chupa. Wisdom became more popular, and building a Tower became more common. Artifacts like the Black Orb and elemental spheres became useful. Players started being more careful when moving around the opponent's territory, conserving mana, and, conversely, the practice of attacking opponents with low mana emerged. Mages finally started being used more often.
In short, the range of methods used has noticeably expanded, which has definitely benefited the gameplay.
Well, that's correct. I'm just saying to reduce its frequency of appearance and add some artifact that suppresses the sphere's effect, and it won't affect everything you mentioned. This would add more variety to the game, and it would also be beneficial for mages to use the sphere (to save their spells and avoid casting expensive spells like those of Wizards, Djinns, and Compys...).
Reduce it in WoTA, but it would be better to add it to CoD, if anything. IMHO
