What quazacolt said, you need to play deepfrost. Note that elemental also does freeze for shatter combos, if u take engineering u can use frost grenade for shatter combos too, swift potion or goblin rocket boots to keep the distance from the rogue. Theres going to be a lot of running and instant cast. Nova-cone-icelance-fireblast.

whats a 37-0-24 used for?

a simple and basic shatter combo is frost nova, frostbolt > icelance while target is frozen to gain +50% crit chance
some complex ones includes but is not limited to: fnova > fbolt + lance >fbolt cast and when its almost finish, pet nova then fbolt + icelance + fireblast

coldsnap doesnt refresh CD, but it does refresh the water elemental summon spell, in which you can summon, use up its mana, elemental death or summon duration, cold snap, and summon another one.

and no, you dont lose lots of crits, in fact, you GAIN MORE crit.

and no, unless the rogue is lagging HORRIBLY without clos/shadowstep and or half/almost dead, spamming icelances and instants will never EVER kill a competant rogue.

cone is barely used by mages for dps, its only served as a backup fnova as it snares better than fbolt. that said, cone overwrites fbolt snare and the snare duration is shorter, so its also a double edged sword.

the only exception would be aoes and/or your target is almost dead and cone would be ideal to add in some added dmg to finish said target off.

typo edit and addins

37/0/24 is either lol spec, or pve i suppose. not much value in pvp.

Don't blink out of Cheap Shot, but Kidney Shot if possible.

Try not to have your Water Elemental too close to you.

this guide is either SEVERELY outdated, or full of fail.

rogues with high ap will have low hp? i lol at that. armory me for more details
then wheres trinket? wheres lolstep? wheres cheat death?

someone needs to update that wowwiki entry already

an easier explanation:

scyap, have you seen or met a shadow priest? have you seen them morphing from holy (or normal) form into shadow form?

that. a rogue becomes a shadow priest for 5 seconds. (same graphic, same sound.)

SL/SL, either felhunter to attempt denial of rogue opener (not likely, unless you got goggles/perception and even then sub rogues have 10yd sap, and can counter your stealth detect via various means/cooldowns) or VW for 10% additional melee mitigation

resil cap along with 12-14k unbuffed hp is almost a must against top tiered rogues. engineering boots/belt will help too, considering its a 1v1 duel. glickz innovated armor setup is also proven to be effective.

do not summon succubus, its a joke against good rogues and will only get you killed, soul linked or not. save your deathcoil when you really need it, preferably after rogue trinket/CLOS, that way you can get full benefit outta DC. rogue needs to cloak sooner or later especially if you start fight out with amp COA, else his hp will dip too low. try to save YOUR trinket for a crucial 6pt KS,
