If you're a paladin on a pvp server, you owe it to yourself to take gnomish over goblin. The deathray is a ranged attack that can critical for upwards of 1500 damage, and consistently does around 800 or so. My friend (a level 43 paladin) and I have gotten lucky before and used it to gank lvl 60s with surprising ease when it criticals. Be aware that it does deal damage to you when you use it, but as a paladin, you can plan around that pretty easy, and frankly, you don't have a lot of options when it comes to burst damage, especially of the ranged variety.
