MP battles we play with auto TMA. Manual TMA would be hard barrier for most of players.
Auto TMA in DW is NOT perfect and sometimes long tracking increases "error". Experienced players knows when solution is good. Auto TMA updating is sometimes delayed or problematic. But works for all tracked contacts - you can save much time for commanding.
In other hand - manual TMA needs longer tracking. Most important is knowledge how to rebuild your TMA work when enemy (or you) make evasion.
Here is single player mission played with manual TMA. Enemy position and range is random. Its almost sub vs sub duel: Akula I imp vs LA Flt III
