Hi KYFT
Nice to know you, but don't know if we have met before, are you playing in
FA?
For your list, I think if that is just your core component for a higher points army, Purifiers maybe great because you can just take droppods from allied detachment now. But for now a roughly 1000 pts army, it is better to take Interceptor instead. At least they could get to flame the enemy early on. As well as having the mobility to get to where you need them.
Strike squad is better armed with incinerator as well, when they deep strike, Psycannon cannot be used in full effect. Furthermore, I would suggest put all the two Psycannons on Paladinin your list to benefit theirrelentless, although I generally think the naked 165pts for 3
TEQ is overpriced.
GK Terminators are better in point efficient wise.
Try to squeeze some points to grab a Liber Daemonica. Rolling one more power on Santic offered more chances to get the power you want, like cleansing flame, sanctury, gate of infinity, etc..
One last thing, I think you may want a Greatsword on the
DK instead of Hammer, unless you have counter Eldar WK in mind (for that concussive). That is just 5pts different and you got right 1000pts army.
