You don't know how to use TA.
1. You use TA only to seal a deal in next 5mins or as your last chance to stay in game when you are heavily losing.
2. If the game is equal and enemy has plenty of AT, why would you call TA instead of Pz4 or Stug?
3. In similar scenario, when the game is equal you DON'T call TA when you hits 700MP. You can call TA when you have like 1100MP so you have extra 400MP buffer to reinforce easily so +120MP income won't hurt you with 400MP handicap
4. You don't need to call TA at all. You even DON'T WANT TO call it as a regular unit unless point 1.
Without TA it's still very useful doctrine. TA is just cherry on the top which you pull out when you are confident you need it. If you pull it out and you have no manpower that's your fault, not doctrine's.
i tested all but vs good alies player going to trouble and they make mines and AT's as fast they saw TA,seems u dont know what topic about,all i said about TA lovers and u are saying u dont have to call in TA at all.
