basiclly what above poster said: Wildfire is your "Burst" button so the primarly MCH plan is to manage ALL cooldowns/abilites around that (well cept Hypercharge thats one takes longer than Wildfire to be ready, but is ready for next wildfire so just plan around 1 hypercharge every 2 wildfires) granted thats the "Optimal" plan & this plan really only works easy at lv70 with the clunkness that is Flamethower. Boss mechanic's & down time do change this sometimes, like if you know they'll be back in time when boss is damagable again, but mostly MCH's "Burst" is every 1 min dictacted by primarally Wildfire.
