BT does an amazing job. They're online EVERY DAY making our mod better. Dealing with often 4-5 topics at a time, which often includes 1-2 doctrines at once. You can imagine that'd be half an hour/an hour a day contemplating and posting. Don't go disrespecting them, it's a tough gig =p.
From what I gather some things just pass straight over their heads, I don't
think they got to look at or evaluate any reward units etc etc. Ultimately as you can imagine, they have a LOT to work on. Priority lies with warmap, as EIRRmod has stated, warmap probably won't be seen until all doctrines are released. Plus answer this, what is the point in balancing doctrines when some are still incomplete? The second AB comes in, people will be like "omg my panthers suxxxx because they get penetrated by everything" compared to them being rape sauce atm. When all docs stay in, then they'd have time to re-evaluate all doctrines.
That being said, often when all docs come in, someone cracks a hissy fit then they'll all get removed and remade from scratch again
