@Cadiz @Gloomy_Sunday and I did the starwater tomb (the eveningstar quest), the traps were all poison, and very strong poison. Have to say, I have done it since and the traps were okay. Maybe some kind of RNG element?
I dont think there is an issue with traps, they should be plentiful and some powerful ones - more because a rogue should be able to get a trap collection for pvp/pve shenanigans. Too many powerful ones can be problematic. I'd say only poison are actual killers as long as you have someone healing on standby.
There is a neg energy trap in Redwood that can be triggered multiple times.
