I dont know how many player want, but for fun, the game need epic traps. My main have tons of trap parts but the strongest traps make 50d6 (max 300dmg) and its a lvl11 item.
New type of traps already would be cool. I think more spell traps or same effect traps, like Wall of Fire, Ice Storm. DC come from Rogua/Artificer lvl + int mod, dmg come from 2*disable device skill.
Any new stronger trap can make me happy.
(Sorry for my weak english, hope you understand me.)
