I think Summoners are fine.

- our SMN play bad (very unlikely knowing him and even that would mean he would have screwed big time to lower our overall dps)

No, this is his/her issue.

I was at ~320 DPS when I tabbed out. It dropped because DoTs and the combat didn't end until it bled out.

Here's no Enkindle/Shadow Flare(more mana efficient and no 5 minute CD):

Another no Shadow Flare/Enkindle, and here it is after they had time to bleed out:

You can also see how broken the parser is, because in the second I tabbed out as soon as my timer went off. The first I was trying to run out of range hoping it would end the combat--I snapped the picture much later. I'm 99% sure Shadow Flare isn't 60+ dps.
