I did 200k FFB into 2x 100k Ice Lance with 200k Frostbomb and 150k Frostbolt in arena today on PTR..
All thanks to the new proc that increases my Critdmg, Mastery and Haste by 50'ish percent.. And it has quite decent proc rate aswell, it always procced when I threw out my first Frozen Orb.. Oh and those numbers are on a Discpriest with Focused Will stacked.
I also killed Discpriest with Focused Will and Painsup up with this trinket proc'd.
On another arena, my Discpriest friends trinket proc'd and he threw me 270k Power Word: Shield..
My Eleshamans trinket proc'd and he casted Lavaburst into NS Eleblast which 100-0'd without trouble, without mastery proc and he wasn't playing Echo even..
I got hit for 120k Glaivetoss aswell when Hunter proc'd his trinket.
Go see it yourself, you can get the PvE trinkets on Niuzao Temple (or whatever the place with Shado-Pan Quartermaster is), there's PvE vendor there which sells those trinkets.
The numbers I've given here is just merely random situations in arena, but if I'd do 100 games in a row, all of them would have massive effect by this trinket's proc alone.
This trinket can not go live in any circumstance.
http://ptr.wowhead.com/item=102293 - The trinket
I had that stacking Int trinket on test aswell, if both of these trinkets proc at the same time, I need about 4-6 globals to finish the whole enemy team.
I had 62k Spellpower, 100% Mastery, 70%'ish Haste and well over Mages crit breakpoint aswell.. Only way to survive the burst is to Block or Bubble, no matter what defensive cooldowns you have, it wont save you.
Just to give you estimate of the damage incoming. This is into a Defstance warrior.
Trinket gets reduced from 84% to 57'ish percent in arena. Oh and remember, Frostbomb, Frostbolt and Frozen Orb is not affected by Mastery in 5.4 for Frostmages..
