Summoner faster levelin the sub class as other classes do?

Hi guys,

is it true that the Sumoror levels the subclass faster so other classes?

If so, it would have to be an insider, or have a logical background that I couldn't find.

I've been told that in the last few days ...

Yes it has a passive that does augment the exp received for the sub-class in the summoner skill tree.

Ah ok, but its a better way to level up the subclass with also level up the diffenrent Main Class at the same time, ... i think...

But nice feature...
