What spec would b better for me spellfire or Shadoweave

Spellfire ... because the Dem spec allows you to increase spell dmg in general not just shadow.

I prefer shadow tbh

omg so many people say spellfire for destro locks
How many locks do you see spamming incinerate in raids?  not many.
And the ones you do, bad dps.

Shadoweave is lock tailoring, then get Battlecast.

You get your crit from enchants, the Int(Stats on the gear and gems enchants etc.)

I mean face it, shadow bolt crits do a lot, but why not max out your reg sbolt damage, because i doubt the spellfire set will make your crit go over 50%, so make the one that happens more often worth it.

Shadoweave = Warlock.
