I will assume you haven't met very good summoners. Where you bard?
in a full CD fight garuda buffed enkindle is almost enough to take down half hp of a bard. We also have um that attack that lowers attack range which can help out a lot
And while purify is the best counter to summoner, as long as we can use equanity (dont know the name of that one either) we can easily get dots back up. Using virus too to prevent some damage.
I think it all depends on when and how people utilize their cooldowns. And people who haven't played a lot of wolves den will not be as used to say one vs one fights.
I also forgot, fester isn't neccessary to beat bards or blms as long as garuda enkindle is up and the pvp skills. We have two instant attacks with 170 potency, which deals a lot of damage with a HQ intel pot and raging strikes on
