Pet xp in Zodias maps

[Bluehazee]

Im not sure if this is a bug or intended, but pets barely get xp in zodias maps.
I was just running event map and my pet went from lvl64 to lvl67 in 30min, while this would take me days of grind in zodias maps. Doesn't seem normal because they are lvl81 maps, i guess it should be at least same as event or hauntlet.

Ty in advance
