Rated BG set for a frostmage.
http://chardev.org/?profile=393421
1) Hitcap
2) 75 Spellpen ( 40 on offhand and 35 on cloak), chardev shows wrong info
3) 4pc brutal
4) 4pc tier 6
5) Enough haste for fast casting, lower global CD and faster CC. With Skull of Guldan used it goes to around 35%.
6) a bit low spellpower is compensated with Synapse
okay. i smell questions like "WTF WHAI NOOB LOW MANA".
Hitcap and spellpen ( enough to beat racial) is needed to be sure that targett will be CCed. Example- you + rogue is attacking a base on AB or eots. You start attacking them, they use pvp trinkets. Rogue sap one guy, you poly the 2nd when rogue is capping the base. If you miss it will be a fail. Example number two- you need to cc one healer when nuking the FC . Everyone in attack group (4ppl) attacks a FC. You missed the sheep- one healer is running around without cc, FC is alive, your grp is dead because you didnt kill a FC in a short time. There are alot more examples of that.
Tier 6 legs- why not Leggings of calamity? Because of 4PC bonus. Yes, 3>1 sockets are cool but they wont give that much as that 5% bonus.
Why haste? To lower global cd, to cast faster, to CC faster, and also to cast more damaging spells while your synapse is active.
Why no resil gems? Because frostmage's defences on rbg are his shield's and iceblock, also lots of CC. If the group can CC properly and entirely control everything on RBG ( incl who controls who and when) then mages do not need resilience.
Blacksmith can be replaced by JC
High ranked mages ( high i mean those who have been top 1-3) will confirm all of that info. Please add this chardev as "Rated bg set"
