I like it bro. Tell me how it stacks up to your former conventional build, I'm sure way better given the fire blade at your lower level is even better than at my level.While my level is nowhere near yours Marco, I am going to try this approach and see its viability.
10/20 lure of fire. Although I've thought of maxing this
20/20 cloak
10/20 lure of ice
20/20 ice shards
Rest into e shield
Blade of fire offhand
Heroic gloves of Haste
I don't have anything else to boost the fire
I just couldn't bring myself to keep maxed fire lure. It just isn't worth it leveling, and since I can't see hits on bosses usually, it is very hard to test on bosses.
Since I go all fire, I only have to worry about one lure, however shards is a pretty nice skill to have. The long cooldown is perfect for this build. Is it worth 30 points though for a lvl 20 shards? Not sure. 30 points into firebolt will give you much better DPS in my mind, but test it if you want.
