Blargchons. Still have? We haven't seen/used Twilight Archons yet. Dark Archons may be in the game but I doubt it.
I really doubt the Twilight Archon will have Mind Control. Twilight Archon replaces the Archon and Blizzard said they have no plans to have the Dark Archon make a return.
I'm positive that the Twilight Archons will get at least one special ability. Blizzard kept stating in their interviews in that they have no special abilities as of now, but are still thinking if they should get one. Perhaps, they already have as the current build, and we are all about to find that out at BlizzConn. Just 4 more days.
Dark Archon can't return anyway. What are you going to make it from? All combinations form the Twilight Archon. Feedback > Mind Control btw.
you know, i was always confused by archons. the spell casting high templar form a fighting archon, while the fighting dark templar form a spell casting dark archon. but anyways, unless high templar and dark templar cost the same, the combination you use will probably effect the properties of the twilight archon.
The twilight archon needs an ablity. It needs an ablity. it is half archon half dark archon. it needs at least one ablity, mabey AOE damage on death or something.
