When playing with both Soul Harvest and Grimoire of Service, how should I use my CD? Simply cast them on cooldown, or wait to pop them together? I'm trying to use Service, Doomguard/Infernal, Soul Harvest on pull, - After 2 min, i Cast Service together with Soul Harvest (Waiting 30 more sec than needed to recast Service)- One min later, Doomguard alone - 1 more minute later Service + Harvest Again - Then after 6 min from pull, my cds realigned and i cast them all together.
Problem Is That doing this way, I waste 1 use of Service. Is it more worth to simply cast it on CD?
