I was actually thinking of putting the reclusiarch in, thats in another list that i made, but i can see where you would want to put in a predator, but in the game ill be using this in, ill be up against a lot of anti-tank, so i probably wont put one in.
As for the power fist, i didnt want to use them because i just feel that no one else will field any tanks, and that i dont intend to attack any IC's directly. So i was figuring i would instead go for infantry muncher.
Heres my new list idea, not many changes but i like it
2 X 10 Assault - 2 meltas, 2 LC = 480
1 Reclusiarch - JP = 155
2 x 5 Dev - 3 missiles = 240
Sanguinary Priest - JP = 75
Sanguinary Priest = 50
