Once a Summoner faces other geared players ranked 30 with ilvl 70 gear Summoners damage drops of drastically Enkindle does around 880 criteria damage on average and Fester does 440 crit damage. Yoshi actually didn't test Summoner damage he basically listened to the under geared players complaining about Summoner damage in PvP in reality if they would gear up then the damage they received from a Summoner would be greatly reduced.
