| Thor is built by SCVs, moves slow as shit, fires slow, and takes several seconds just to turn around. Units like stalkers could easily blink behind, fire off like 4 shots, then blink back to the other side before thor can turn to attack. Cobra's are fast enough to mostly circle and fire on thor, killing it and barely getting attacked by it.
Great for Artillery tho. Needs good AA, siege tanks etc. support. |
