1. Space Wolves = No. Salamanders = Perhaps. I do not see any reason as to why not.

2. NO!!! NO, GOD, PLEASE, NO!! NO!! NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!

3. Not too large. 50 or less. Exceeding must have a reason as to why it is larger. An excuse could be that it is a former faction that got conquered. Still-existing factions shouldn't be larger than 50 worlds, unless a good reason is given.

4. Depends. I cannot say no to high-tech xenos, though, since I myself possesses a really high-tech xeno race, no matter how little I edit them. I like high-tech xenos, personally, but they can't be flawless. If the technology seems flawless, then no. If it has a weakness, then yes, depending on how large the weakness is, or if it is a multitude of weaknesses.
