Blackheart's Bay On Blackheart's Bay, I recommend sitting in top/mid lane that way you have access to 2 lane's worth of regeneration globes, as well as the 2 pirate camp globes as well. Uther doesn't really have great chest clear, but you could combo down the last couple hits very quickly with Hammer of Justice Holy Radiance Divine Storm

Cursed Hollow On Cursed Hollow, I recommend Uther to be middle lane. This way when ever a tribute spawns, you are closest to rotating to the tribute. Most fights on this map happen around the tribute, so having a healer there for the fight is a must. When you get a curse, don't forget to group up with your team and push, since, big surprise, Uther is not a good split pusher. While you can gather a tribute, I generally recommend against it since Hammer of Justice Divine Storm Divine Shield

Dragon Shire On Dragon Shire, I recommend Uther in bottom lane. This is because you can cover the lane while your teammates clear a siege giant camp, then grab the heal globe and heal your teammates back up. Since you can heal yourself, you are pretty good at shrine control. If your team is trying to channel, you can stand on the shrine and prevent the enemy team from taking it, then try to meet back up. I do not recommend taking the dragon knight yourself since you are probably the only healer on your team. You can heal the dragon knight so don't forget that, especially on the first dragon knight since it has a low health pool. Since you are melee and don't have strong damage output, I would recommend against trying to kill the enemy dragon knight yourself, and instead try to heal your teammates that are doing the damage. If you went Divine Shield

Garden of Terror On Garden of Terror, I recommend Uther to be one of the side laners. That way once night starts, you can either hold lane or clear the plant camp that is on your side of the map. Most people overlook clearing that, but they are fast to clear and give decent experience. Also since you are stacking regeneration globes, I would recommend you stand near the golems when you kill them. Usually when you are Uther, you are the main healer for your team, so I recommend not taking the plant terror, and let someone else take it. You also can't heal the garden terror. When the enemy has a terror, watch your feet and if needed, you can Cleanse
