dominion wont be balanced for champs. just like twisted tree. the game does not revolve around these maps. they are extra choices I assume certain champs will fail hard on dominion.

Junglers will be fine. With the whole faster gold hting and less of a laning phase (Which is why many junglers were forced there to begin with), they won't be as weak in Dominion as they are in laning on SR.

Trundle will prob be good for defending nodes since he can use pillar and has his little aoe thing that increases his movespeed and other things.

Yea how will trundle suffer when he can have his steroid up almost always when he puts it down near a capture point where there's a lot of action. you'll just have to play him slightly differently is all.
