Looks Stupid
Only thing needed to beat much higher skill players was to mix up wraiths and banshees. No need for scouting, no need for jackals/hunters. No need even to take enemy’s hook.
It is enough for Brute to control his hook to (almost) double pump mixture of banshees and wraiths. It is pretty stupid. I saw how hard I MarcoStyle NL and GGC KenZboT were trying. Scouting, trying to ram brutes, microing spartans to take wraiths. All for nothing.
My friend made even huge mistakes (like selling accidentally his 99 % complete warehouse which was 3rd building). Still he won easily.
Flamers/Spartans/Hogs are not any good when outnumbered by wraiths/banshees. It takes same time to train wraith and hog (26 s). Covenant can train 2 x Banshees (15 s) while UNSC gets 1 x scorpion (36 s).
Supplies Required per Minute for Covenant:
To single pump banshees : 200 x 60 / 16 = 800
To single pump wraiths : 350 x 60 / 26 = 808
To double produce banshees : 2 x 200 x 60 / 15 = 1600
To double produce wraiths : 2 x 350 x 60 / 26 = 1616
To single pump banshees + single pump wraiths : 800 + 808 = 1608
Production from 4 x Blessed Warehouse + 1 x elevator = 1305
Production efficiency : 1305 / 1608 = 81 %
Supplies Required per Minute for UNSC:
To single pump hogs : 350 x 60 / 26 = 346
To single pump scorpions : 500 x 60 / 36 = 833
To single pump hogs + single pump scorpions : 346 + 833 = 1179
Production from 3 x Heavy Supply Pad + 1 x elevator = 1125
Production efficiency : 1125 / 1179 = 95 %
Conclusion
By controlling at least one supply hook Brute chieftain can produce wraith against every warthog (grenadier) and 2 x banshee against every scorpion. If UNSC goes to tech 3 he has no supplies to build army. Brute needs only Temple without upgrades (saves money compared 2 x reactor, 400 + Brute Chieftain vs 750).
P.S. Please, prove all this wrong. O.o
