The traps as they stand now are broken, you should not need 15 perception to see a simple dart trap, especially in a so called "early mid game" area based on player level. Especially when you consider that springing a trap = 1 wound at minimum, possibly more, and taking even 1 wound seriously impairs a character.
Trap detection should also not be tied to perception when the mechanics description in game says it is tied to mechanics. It is a beta but jesus, if you knew this wasn't true update it before release.
That said if the original backer beta for Eternity 1 taught me anything, Obsidian intentionally releases the beta overtuned and far too challenging at first then scales down. The bad builds of your included party members, and the fact that you have way less gear than you would in the real game doesn't help either. So likely they intentionally made the whole initial release more deadly than it really needs to be.
