Is it worth bringing a summoner to raids?

Here's the thing though. When a Summoner dies, they automatically lose their pet. 25% personal weakness, with your pet that is also dead and 20% of your dps gone. That's 45% of your dps without your pet having weakness. With how stats seem to be snapshotted, Just makes a bad situation, even worse.

Let's say your pet loses 20% of their dps,

The loss from not having a summoned pet is only really relevant if you don't just swiftcast (or hardcast I guess) it back after you die. Also, if it wasn't effected by weakness, you'd actually be less effected by death in that 20% of your damage remains untouched. However, there's also the issue of death screwing with buildup that hurts the burst-phase heavy summoners pretty badly.
