After more setbacks then could be expected or anticipated including loosing internet for the past week, here I am with my Comp entry.
Real quick, do note that I would classify this as a competitive list, but not in the conventional sense. I would argue that the only real way to win games with the 7th Edition Ork codex is via objectives, and to that end this list is written with this in mind, on a table that is plentiful with terrain (preferably Ruins, which at least in my area is the norm), and using the core Rulebook Tactical Objectives. Without any further ado...
The Min-Max Objective Grabbaz!
Painboy w/Finking Cap
2 units of 10 Grots and a Herda
3 Trukkz w/Rokkit Launchas
unit of 3 Lobbaz each with an Ammo Runt
SAG Mek w/Eavy Armor, Gitfinda, and 1 Ammo Runt
10 Grots and a Herda
11 Grots + Herda
2 units of 3 Meganobz in a Big Shoota Trukk
1 Rokkit Buggy
2 naked Dakkajets
Warlord Painboy goes with the Lobbas on or near an objective in heavy cover, if at all possible outside of enemy LoS (since barrage weapons don't require it, and we want to keep the Warlord out of fighting to deny Slay the Warlord to the enemy).
The SAG Mek should be deployed like all SAG Meks, in heavy cover with good range of the field and with a Grot bodyguard. Now I'm not going to lie, the good old SAG almost didn't make the cut since he is such a high priority target, can blow himself up, and can be precise shot by the plethora of Snipers that exist in my neck of the woods. For those reasons I would recommend against putting him on an objective, it just makes him more of a target.
As your primary objective grabbers you have the Trukker Grots. Yes thatís what those Trukks are primarily for! To this end play them carefully, donít jump an objective unless you need it, or are attempting to deny your opponent from it. Much like the Trukks carrying them, they will fall apart like tissue paper from enemy fire, so use them with care. To that end, I do not advice attempting to deny an opponent objective with the Grots, unless itís a dire situation.
The Meganobz are your heavy hitters, but even with their armor save they are a far cry from invulnerable. They are best used in this list to take out enemy objectives (big surprise the whole list is dedicated to objective grabbing), but donít go overzealous with it. Once they loose their Trukk they loose a huge proportion of speed.
Your lone Buggy is for Outflank Armor attacks, and will likely be a One Hit Wonder similar to the previous codexís Green Baron. Hope for a good Outflank and hit them with your luckiest D6. Even with the changes to the Vehicle Damage chart, that extra Rokkit can and surprisingly does often times make a difference.
The Dakkajets are your big distraction and can lay out a fair amount of carnage, especially if your opponent is bringing the airpower. Their first and really only priority other then general harassment is taking out any Valkryes, StormTalons, or other hard to hit buggers.
And thatís the Min-Max Objective Grabbaz... OR IS IT?
Advanced Play Theory
On Warlord Traits the big one to hope for is #1 of the Strategic Trait table (ref pg 125 BRB), which we have to roll on with the Finking Cap regardless (I point out because that little caveat is often overlooked by players). For the secondary trait (or really the first if you want to be precise) I recommend the Tactical Traits table, hoping for a 1, 3 or 5. Personally this is the only time in 40k that I hope for Snake Eyes, as those bonuses will work best for this list.
When you first analyze this list and playstyle, you may feel inclined to separate the Meganobz on different flanks, but it has been my experience that its best to keep them relatively close to one another and double team your enemyís objectives. All this said, their primary target should be enemy Troops, ideally those with little or no offensive CC power (ie Guardsmen, Tac squads that have been combat squaded and lack the Sgt Pow Fist/Pow Wep, Guardians, etc).
If facing an exceptional cheesy list with an enemy Imperial Knight, the Dakkajets are your best defense, and I strongly advice the two pronged attack where if you can pull it off, both planes are attacking from a different angle, that Ion Shield canít be everywhere after all!
The Very best of luck to all you Ork players still out there! Keep it Green and hold the line, one day weíll return with a decent codex and krump the ooniverze again!
