Hmm, as you brought the SC2 topic again... here's my reply:
I though Twily to be more like the Protoss Mothership from Legacy of the Void version... or how it was in the Beta release of the game ( I hope you know it, you can check the mothership trailers before the game's release), before crybabies reported it so much until it lost all of it's powers , ALL OF THEM, in exchange it received "the toilet"... that the only thing it does since some patch is to give invincibility to the enemies flushed. That's about when I gave up on Starcraft 2, and I was from the last once, as quite many other people, since I saw the Starcraft (the 1, Broodwar) with SC2 mod (to have all what SC2 has, except the HD models), with better balanced units, where the Protoss Mothership could fit in there with all it's original powers. Because you can only have one, and it costs more than anything, especially getting to it (to unlock it), of course it was supposed to beat a Battlecruiser on 1 vs 1, terrans could have as many thors as wanted, and it was done as a simple air unit, not special building and stuff like the Mothership.
So, yeah, after finishing the Wings of Liberty campaign on a pirated game, made my own version of the Protoss Mothership as a mod, played with it around some maps, and it's powers like the one visible at the hostile Mothership in that same campaign (yeah, that planet cracker...), had a lil fun, and abandoned it with the though of not getting near SC2 until LotV, just did the HotS story like 2 weeks ago to check on the story to know everything for the 3rd release, where so far it's clear, the girl controls the Zerg, and the boy controls the humans, all perfect for teaming up under the Protoss's wisdom to beat something untouchable, as Kerrigan admitted they can't win no matter their numbers, but they won't just lay down and die. The Protoss will bring the solution to that Afterall, Kerrigan got ready for it thanx to the Protoss, or well, Zeratul, who already has the plans, just had to wait for the canon fodder to get ready.
So, I actually prefer not talking about Starcraft at all, since just remembering their name makes me want to throw insults around... not a big deal though, their game, they can shit on it, but they shouldn't have wondered when it got out of beta, only half of the testers actually continued and got the full game.
