IMO, priority level project plan from left to right on each color, and not spreading level, focus one hero on each color.
Red: Finish Hawkmoon 3.44 to 3.50 (max), Boldtusk ASAP, Marjana to 3.70, finish Nashgar to max, 2nd Kelile to 3.60, Colen.
Blue: Isarnia to 3.70, Grimm, Sonya, Ulmer (great for fast tournament), 2nd Kiril
Green: Melendor, finish 2nd and 3rd Caedmon, finish all almost max.
Yellow: finish all almost max
Purple: finish all almost max
Defense: Caedmon - Gormek - Boril - Li Xiu - Rigard
Attack: normally it depend on opponent tank color, and we bring more strong color, so if tank color is green, then we example we bring 3 red, and see if we need dispell or not, if opponent has many buff, also need cleanser if opponent debuff or burn our heroes.
