DEX over INT (pve) seems totally fine. It's just when it comes to (pvp) INT is what provides your staying power and the ability to do constant damage. (Lifetaps / Asystole / Boil Blood)
If your lifetaps land they also allow you to stay in on mobs through AoE's without taxing healers. Most recent use besides tanking Kunark content we've found for SK's is to let them tank Halls of Testing. You can slow the mobs immediately with the snap agro.
