I pointed out it's ridiculous for it's timing and cost and outright game ending if you and your teammates dont prepare Ostwind rush right now. And thats a tier 3 same fuel cost as single T-34.
Timing:
Ostwind 40 + 90 + 15 - 20 = 125FU when rushed
Cost: 90FU
Centaur 30 + 115 - 20 = 125FU when rushed
Cost: 100FU
Performance: roughly equal TTK as the Centaur in several scenarios (disregarding representability of number of tests because I can't be bothered to do more for you)
If you think the Ostwind's AI is 'ridiculous', the Centaur has been ridiculous for years now.
