1: They receive such training at the Schola Progenium and the Orders Militant of the Adepta Sororitas, due to their connection with the Ordo Hereticus.
2: Combat Resolution in an assault. If you think Stubborn is effectively useless, then you don't know 40k very well.
3: [url=http://en.wikipedia.org/wiki/Accurizing]Educate yourself.[/url] Effectively, this is a standard weapon that has been tweaked and customized to be more accurate. This happens all the time in the modern military, and I have no problem seeing a Mechanicus ritual (performed for a fee of course) to convince the machine spirit to fire more accurately.
4a: No they aren't.
4b: Two twin-linked bolt pistol shots.
5: And you get a model that is effectively a Celestian Sister Superior with two wounds for that. Only without Holy Hatred.
6a: What? You're saying a 2+ save is worse than a 3+ save? Try being more coherent.
6b: Read the fluff behind the unit.
6c: Read the fluff behind the unit.
6d: I disagree.
7a: Granted to the Sororitas by the Ecclesiarchy.
7b: I compromised between C:IG priests and C:WH priests when I producd that statline and equipment.
8a: I see no reason why they should. They're still just S3/T3, even with their occasional boost to initiative..
8b: I can do that.
8c: And yet you whined about them being good in point 8a. How ironic.
9: I don't think so.
10a: Maybe. But you misspelled the name of the squad.
10b: Seen, and ignored for being wrong.
10c: Which would not properly emphasize their role as mid-ranged damage dealers.
10d: Apparently it's not.
11a: They fire them at BS3, however, and they're still S3.
11b: Look up Squad Designated Marksman.
12: Chapter 9: Units and Rules Under Discussion
13: They have the same statline, but have Scouts instead of being Scoring. I don't see why they should have an increased price.
14: I couldn't care less if it offends you.
15: Tell GW that. Also, no.
16: Same cost as assault marines, but without MEQ. Deal with it.
17: Chapter 9: Units and Rules Under Discussion
18a: Predator chassis vehicles all received price reductions in all Imperial codices. This one got the smallest of price reductions.
18b: It is, just a few points shy of that.
19: Chapter 9: Units and Rules Under Discussion
20a: It gives up large blast to instead have a 1/3rd chance to melta. That's hardly more of a "monster" than the LRBT is.
20b: Don't care, too bad, so sad. Already been discussed to death, and my reasons for making the decision have been stated and overstated time and time again.
21: For someone whining so much about the fluff, you appear to have forgotten the holy trinity of Sister weapons.
22: And in this case, the model still dies, but its passengers survive due to the sacrifice of the crew. It's less complex than Orders at least.
23: Deal with it. It's basically the same price as the current one, I just added +1 to frontal armor.
24: Deal with it. It's basically the same rule as Marines have with their Rhinos, only I gave it a name.
25a: That is the rule as it is. See the C:WH FAQ.
25b: I made her worth taking compared to other similarly priced models in fifth edition codices.
25c: It does have a limitation.
26a: Then suggest a price.
26b: Suggest an alternative. These are GW's rules, not mine.
