I would like to see deadlier traps. I don't know how many groups the I have joined that have skipped the rogue for another class, since the traps were easy to get through or bypass with enough evasion or hp.
Spiked or blade traps that possibly stunned, paralyzed or harried you while passing through, long enough for the trap to respring and cause more damage. Maybe even poisoning them would be a change to.
It just seems that most rogue are often ignored because the traps just aren't challenging enough or don't enough damage until they are on elite or epic levels.
I personally prefer rogues in parties, not only for traps, but they are awesome DPS.
