70 points s for a 2w, t5, armor it doesn't matter because everyone has ap 2 now anyway, think I'll pass on centurions. Save room in the buget for sternguard and more tac squads.
The devastator tactic for ultas seems great though, devastators with relentless, yes please. I think I might put them back n rhinos and shoot out the fire ports while drving around, loose two shots but gain av 11 for as long as the rhino lives.
