I think the actual issue is that
1)It screws up the order of rotation of the brd's, because cor is slower obviously(Biggest issue)
2)Cor's dont merit that way
3)LS's dont ask them to
4)Cor's like QD merits
5)Cor's like Fold (I think its useless if your smart enuf not to double up on 6)
lets look @ the right merits for a workable rotation
5 Winning streak merits Phantom Roll lasts for 6 minutes
5 Recast Merits and Phantom Roll Recast becomes 50seconds
You'r right cor can reuse the same rolls on it unless theyre wore off already but it wouldnt be hard to just pick a differnt roll. 1 Preferably that has a supercharged effect for that party, We have wayy too many to pick from in the first place.
The only other issue is yea, 1 buff per 3 PT's (6 Rolls) would most likely be down for 10-15 seconds due to unlucky rolls of 1's and 2's.
Big question is where does Haste and -Weapon Delay cap out
