First of all, let me say I played dominion in the first days of it's release until I decided to stop and now I want to come back to it. I don't know if all champions are viable to the map, but I want to have an answer for that. I'm also looking for strategies on how to survive the most on this map. Thank you for your attention.

Most champs can do well in Dom. Some better than others, but if you play a champ well, there is likely a place for him in a Dom team.
