Whatever is your expertise, while shld be min 5 exp (from talents), build anymore of that is just waste of any other valuable stat with real output dps. If u get Dodged by boss, u will need to only redo de hability. Also de Probability to get Dodged 3 times in a row with pleague strike shld be around 0,000029% wich will occur once in 34,843 cases... don't worth it, just re hit the ability.
Well, it is nothing new tbh and is even mentioned in the UDK guide from Gnimo that no-exp UDK has POTENTIAL for highest dps at BIS.
FDK however has so tight rotation that you cannot afford ability recast if dodged without adjusting rest of the cycle and you still might miss next Pesti -> huge dps loss.
using a dummy isnt the best way to test out stuff cuz the dps is very inaccurate its more better to compare on actual bosses that is a single target, but yeah no exp has the highest potential dps but u are more likly to get dodged/parried with plague strike or scourge strike icy touch is always hitting cuz its a "ranged spell", say if ur n RS HC tho it would be very helpful to have a offset build for exp so that way u dont kill the tanks by parry haste....
