I have never seen a quest or quest chain with 50+ traps. I have seen quests and quest chains that run through an entire backpack slot worth of cure light wands.
That being said, this:
is great.Besides, my rogue also carries around 25 rez scrolls, 25 crit and serious scrolls, 50 or so cure light, and a couple of wands, plus a ton of pots for self use. As a rogue I am not the party healer, but if the group has split up or there is only one healer in a raid, I can do my bit to help out.
