I picked Mordin for the escort on the playthrough for the no one left behind achievement, but on my current insane playthrough I am trying to get as many killed as possible for fun so no loyalty missions and pick all the wrong people for tasks.
I might select someone like Grunt for the escort mission cos he is tough and the squad could use him in the last fight against the collectors. Hence, more squad members should die. I might even be able to get shepard killed (it's ok I already imported this shepard into me3)!
Two words: freakin' awesome, right from the start! Got me inspired a long, long time ago... Even did a pic because of you, but couldn't turn the ugly hand-drawn draft into something usable - XNALara didn't want to run. But since I finally DID manage to make it work - here's said picture, with due credit. Hope you don't mind lil' me feeling a bit inspired? Anyway, keep it up!
Did you question why Ashley wasn't taken just to make that joke or do you really wonder why? Because didn't you attack the Collectors before they got to Ashley (there were other Colonists still just frozen around too)?
I admit you make a good point, I once thought this as well: Since Ash was frozen on Horizon along the colonists, why did not the collectors take her? Seems only logical to me...maybe she scared them away with a hidden cross or something?
Thane is not ment for the vents, only Legion and Tali are. Team leaders are Garrus or Miranda. Bubble girls are Jack and Samara. Escorts are Jacob or Mordin. Your Final Team should only consist of one Tank and other squadmate that isnt (that makes sure the left team would all survive) This of course if you have all the upgrades and all loyalties before this.
A small correction, if I may, Legion, Tali and Kasumi qualify for tech expert, escort should be the _less_ resilient one (Mordin, Tali, Jack, Thane) and those best to bring to fight the Human Reaper are also the less resilient ones. The most resilient ones, like Grunt, Jacob, Zaeed and Samara should stay behind and not be with you.
