I agree very much on the wider vs higher thing. The recoil (especially on the Shuriken Catapult... not actually convinced it has any at all) is negligible compared to the horizontal spread.
So long as Orks are suitably advantaged in other ways to compensate for that disadvantage then it's all good.

The suggestion someone made about reduced TK respawns would work nicely and be very Orky.

I want the propa Kommando bits! Goggles on me 'ead, A big ol' backpack, purple war paint, and a cigar stickin' outa my grinnin' mug! Also a snazzy coat and spare magazines!

Scars that give you toughness

Bionic implants from the painboyz ( i remember i had one with no legs and half of a motorbike instead, a metal one from gorkamorka game)

Metal skull.

Squig hair.

Bionic eye.

Darker green

Oi'd be a kommando if derz a blundybuss innit fer me! Alzo, snikkin' gitz sounz loik a gud laff, don' it?

Snikkin' gitz is ALWAYS a good laff!

Also since they aren't available as weapons yet, they should add decorative Big Choppas as back items! Or an extra Shoota! Or two extra sluggas in snazzy holsters like the Black Reach Warboss! Also Also, Knives for Shoota Boyz melee weapons!

I would like the ability to change the face of the Ork. Some with scars, some with more scars, some with bionics etc etc.
And I also would like some armor replacements that remove the chess-patterns. I know, those are Ork-trademark patterns, but I've never liked it, just not my taste. I can live with some of it, but not both whole shoulder plates. That's too much for my taste.

I know it's early and probably will be better (for me) armor replacements further down the line. I'm just speaking on what I've seen so far.

A cybork armor upgrade would be cool.

Also, I need gold teef for my Bad Moon. The grill needs to be flash.
