Basically just posting to see if anyone has any advice or changes for my Ork army list i'm looking to run at an upcoming tournament

HQ, Big Mek, kustom force field = 85

Elites, 9 Lootas = 135
10 Lootas = 150

Troops, 20 Ork boyz, 2 Rokkits, Nob, Power Klaw, Bosspole = 180
20 Ork boyz, 2 Rokkits, Nob, Power Klaw, Bosspole = 180
19 Ork boyz, 1 Rokkit, Nob, Power Klaw, Bosspole = 164

Fast attack, 4 Deffkoptas, rokkits = 180
4 Deffkoptas, rokkits = 180

Heavy, Battlewagon, Deff-rolla, armour plates, grot riggers, 4 rokkits =165
Battlewagon, Deff-rolla, armour plates, grot riggers, 4 rokkits =165
Battlewagon, Deff-rolla, armour plates, grot riggers, 4 rokkits =165

Total = 1749

So yh there it is basically, lootas stay back, the boyz ride in the battlewagons and go krump things with the mek, and the koptas make a mess of any other tanks
