Please, respond here only in case you've played against this tactic.
Predator Destructor is excellent. It can neutralize a crowd of tankbustas in two shots; it can counter killa kans, deff dreads, even big trakks!
Of course, if we both - SM and Ork - are in the late game, I could do a lot of stuff to counter these tanks: for example, make a lot of Big Trakks and utilize my better attack range. But I feel lost when I see predator destructor spam from the 11th minute of the game. I could stun one tank, may be two - this is not a problem. To this moment I usually have two deff dreads, 3 tankbustaz and my heroes. But I can't actually kill these tanks, I just damage them and force them to retreat for repairs. 3000 hp, I mean, with the Shield doctrine! Without upgrades! Where is my 3000 hp tank? Oh, I have only 1800 hp tank for greater price. So, when my dreds are chasing predators, they just use their reverse mode and keep shooting at me, while retreating to turrets and handy servitors. At 16th minute I usually stand against 3 predators, and I have nothing to counter them. They just obliterate any unit I build. Even unexperienced novice SM could easily beat me with Predator Destructor spam. I tried to spam Killa Kans, tankbustas - nothing helps.
If you know, how to counter this spam in the mid-game (from 11th minute to 20th), please, share your experience.
