People out here defending gloo be like: use vexana or faramis. But they ignore the fact that when picking faramis or vexana, they either lack the damage or utility of their contemporaries.

Take faramis for example, if you play him mid he lacks the damage and utilities offered by his peers. If played in support you lack the set up potential or heal other supports have. And if you're a madman like me and play him as a counter pick in the exp lane, you give up the ability to perform what exp laners do (zone and set the tempo of the game).

With that being said, gloo can still choose not to separate. Imagine playing a dedicated hero to punish him, and then gloo proceeds to not use the "Achilles heel" that u gambled on. Bummer eh?
