Akaitsuki I love your little background fluff of your Wyrdboys and so want to see a pic of them. Its the little things like that that which is why I love Ork armies so much, and what I feel other armies so often lack.
With your army do consider giving the Boss an Attack Squig (I feel I'll be saying a lot in this edition). For the basement bargain of nothing, nada, zip, and zilch it'll give him a couple extra attacks, look stylish, and make him very old school (which in this edition just means its new again, the 90s are alive in 8th). Squigbombz also (surprisingly) have that same unbelievable point cost so take 5 (because you can't take 6 and still fit them in a Battlewagon).
Maybe its just my personal opinion, but I feel that you'd be better off by dropping the second Waaagh Banner. If you do you can grab a Kannon and 2 Big Shootas for each Wagon AND a Grot Orderly for the Dok (think of him as an Ablative Wound for someone you know is going to be an enemy high priority target) for a 2000 point total. As an added bonus this would also slightly lower your Power Level (although frankly I can't tell if that's the kind of thing that's going to be a necessary consideration with army building or not).
