For the first time in our guilds 12 month history there were 10 core members online on a Saturday night and we decided to do an impromptu raid. Needless to say, everything went cruisy and before we knew it we had deathwing down (only making the phase 2 transition by 2 seconds, but that's another story). On account of being the only non-lengendarified spell dps this was mine for the taking, Rathrak, the Poisonous Mind.
My initial thoughts on the item -> no green stats??! Compared to my heroic volcanospike this is a loss of 139 haste and 119 hit, however my stat weightings suggest that this is more than made up for by the 23 int and 309sp (probably offset by the loss of an immolate tick if I'm destro). This is particularly interesting because it helps to improve my reforge options, by essentially giving me more pieces where I can reforge out of crit/mastery (I'm currently playing aff/destro).
So it seems that it will be about equal before considering the proc.
Equip: Your harmful spellcasts have a chance to poison all enemies near your target for 8710 nature damage over 10 sec.
After searching around on the internet I think I've found a few things out about it. Supposedly the proc
-Has a 15sec icd and a 15% chance to proc
-Doesn't scale with spellpower
-Doesn't proc off dot ticks
-Does scale with talents and other non haste based modifiers.
With my technically incompetent and most likely grossly incorrect maths that means 6.66 casts would be the expected requirement to cause a proc and I estimate a cast occuring once every 1.2s. it would take about 8 seconds for it to proc, so you get on average 1 proc per 23s. Dividing the proc damage (+10% spell damage taken) by 23 seconds gives 410dps or the equivalent damage of about 220 haste, putting it about 50(?) stats below item budget. Because the proc is static the item wouldn't be expected to scale as positively with other gear as other pieces would.
So I guess it should be a pretty upgrade. Does anyone else with the item have any thoughts? Evidence of how much damage it translates to in the real world or ideas of fights where the proc might be useful. Madness of Deathwing comes to mind but I'm really not sure that it would add that much as adds can rarely be expected to live for 10s and that's IF it procs right away.
TLDR: Deathwing spelldagger is weirdo.
