I guess people need to start the armies' tacticas all over again, so here is the new daemonhunters tactica.
I'll start with the Inquisitor lords.
inquisitors if used right can be very deadly, they can be any type you want:
-psychic power whore ( )
-you want at least one mage to give your inquisitor BS 5 and a couple of gun servitors (i personnaly get 2 heavy bolter ones because if you have 3 you will start eating up points too much)
-A mystic can be a good choice if you are facing any deep-striking/drop-poding enemies because he allows you to shoot at them when they appear.
-if you are facing against shooty armies, you can get some acolytes to be your meat-shields against all those pesky guns.
-maybe give your inquisitor a psychic power such as scourging against weak enemies.
-And finally, don't forget to equip your inquisitor with a good gun!
-acolytes are a must-have for me, it's like having 5/6 wounds in your inquisitor, they will help you defeat nearly everything.
-familiars and hierophants are a must as well, they give your inquisitor +1 initiative and leadership.
-get only one combat servitor because they are a waste i think, but give a nice bonus to your WS.
-if you don't choose a familiar, you can equip your inquisitor with a thunderhamer/daemonhammer .
-also a REALLY good combo against daemons is:
-Grimoire of true names
i know that this is a bit expensive but you get absolute pwnage against daemons
I never really tested this type so i don't know much about how they do in battle.
-familiars give you one more psychic power to choose from, but you can only use one each turn.
sorry i don't really have any knowlege about psuchic oriented inquisitors.
Continued later, maybe ill give examples of Inquisitor lords.
