My point was is that Ostwind is anti-everything. I never claimed it's best anti-tank unit there is. 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.
Have you ever seen what an t70 can do to axis players that do not prepare for it with any at units or get outplayed? same goes for m20s, UCs, M3A1s or WC51s there are plenty of gamechanging units that can be really effective with the right timings (there are often similar issue with people complaining about tiger rushes in 4v4s). Maybe you should upload a replay where the unit is gamechanging, you might always lose with bad teammates after unlucky matchmaking or if the matchmaker has to guess the elo+ for new teams/players - but if you play on a similar level (with similar mapcontrol, good decision making roughly same apm or awareness for ambushes, grenades and mines) then a proper replay might help others to recognize the ostwind's problems or help you improving your own gameplay.
