EPT1.Just as CowGoMoo said, it would be weird if HTs have Feedback, for ghost is Terran's answer (and maybe the only answer) to Protoss's HT and Psi-storm.
2. It is said that Feedback has a super long casting range, thus, as one of CowGoMoo's opponent said, Terran should use sniper round to counter HT instead of EMP round, and the game turns easily into a tedious micro war, for who throw skills faster has a very large opportunity to win.
3. Although Psi-storm is nerfed, HT is still a little too good. Strom is good against almost every unit of every race, so adding another awesome skill to HT may make it even imba and overused.
4. Twilight Archons are rarely seen in all matchups, so rarely that it reminds us Scout in Starcraft 1.
TAs seem to have lost their position in Protoss Arsenal, for other units, like Collosi, Immortals, Void Rays are doing better.
We may chage this situation if we grant Feedback to TA. With Feedback, TA will immediately find its role as an awesome caster-killer.
5. EMP in Starcraft 2 decimates only 100 shield, it's not deadly against Archon any longer, and with its decent attack against bios, TA will be a very good counter against ghost, and even HT, Infestor,etc.
6.Lorewise, TA is more or less a merger of Archon and Dark Archon. There's nothing strange that TA inherits anti-caster ability form Dark Archon while working as a heavy assault unit like Archon.
Any ideas?
Edit: Feedback is already in the game, I made a major mistake.
