So, played my Orks for the first time with the new rules, this time without forgetting some of the rules like I did with my CSM, and got crushed by an IG Mech Guard list.
Long gone are the days when a 1/2 dozen boyz could run up to a Leman Russ, punch it a bunch times, and glance it to death with it's measly rear armor of 10 on the 1st charge. Now, even with 12 boyz and a Nob with power Klaw, those things WILL NOT DIE! It's always been a problem for Orks to deal with vehicles, but once we got into close-combat, it was less of an issue. Even Chimeras take over a turn to kill in CC! Meanwhile, out jumps his vet squad with flamers and WOOOOOSH! Dead Orks everywhere! I lost over 30 Orks in one turn, from less then 1/2 his army shooting at me.
The ability to fall back and to let others open up on the enemy you were engaged with is VERY powerful, especially for a gun-line. Even the dudes that fell back can shoot at you with the order "Get back in the fight!" which now happens automatically, you don't even need to roll.
Time to re-think the Ork statergy. LOVE the fact we strike first on the charge, it's amazing, now just have to find some type of long range, dependable anti-tank stuff for the greenskins. Lootas? Tankbustas?
