while the new trapper change of only being able to see 3 roles is nice, in effect its very rare for this to happen and even confirming up to 3 townies is extremely strong. Its also annoying that judge is the only NP that cant do anything about mass confirmation, I dislike when town plays sloppily and gets bailed out by winning a 1/3 (see jinx). This is why I propose:
When a non harmful evil role triggers your trap they will instead dismantle it.
"Your trap was dismantled by a Witch!"
if multiple evil roles visit the trap you see all of them
you do not see any town role triggers if an evil role dismantles your trap.
This keeps trappers ability to confirm a townie or 2 throughout the game with more hidden traps and catch evils out not visiting them, while removing its ability to effectively mass confirm outside of TT hunt, which I think is a positive for both playing with and against the role.
