Personally, I feel that the song of flame perk is a great team perk but most sunsingers will choose the self rez. I feel that activating the super should automatically trigger song of flame, and provide faster health regeneration or over shields to nearby teammates. And maybe one grenade choice like solar flare, could be thrown to create a healing aoe and have the fastest cool down. To keep it balanced it would do very minimal or no damage at all the enemies. This would be a nice team ability. In addition, the warlocks melee hits anything on the screen( to op!). So maybe the melee could heal teammates. Instead of scorch, maybe something else that has a pretty short cooldown, blink strike with fast twitch fast. U could melee teammates with same range for warlock melee and provide a light over shield or quick constant heal regeneration for a short time. This would make the sunsingers a different and interesting sub class instead of a grenade spam. I feel that all these changes should be choice options for sunsingers so players can be a healer if they want to or be a grenade spam. Also, I feel that the defender should be more of a tank. Maybe abilitys to pull agro and have a good chunk of bonus health. Just my 2 cents
