Hi there, love the XR rules so far. I had a few question regarding the Ork XR rules. The Ork Clanz has some upgrades and gubbinz that are not in the Ork XR rules, was wondering why some of the upgrades were not put in the new rules. Specifically the tellyporta, shokk attack gun, and assault karrier rules.
Also, it says in the Ork XR that you must replace lances and nova cannons with the ork version. When taking an imperial cruiser with a nova cannon, what would the strength of the killcannon be, and also when replacing lances, is it a straight replacement or do you get a d3 value?
Regarding the gubbinz: When the Orks went through their complete overhaul (I'm really going to need to leave a note about that in the log), they were basically rebuilt from the ground up by Khar and the rest of the BFG:R team. There's not a lot of discussion that I can find on the forums about why some of the stuff was not carried over in the new version.
For the Assault Karrier, I can speculate that since Orks now have boarding torpedoes for free all the time, there's not a particularly strong reason to have a conditional "+1 bay strength but no fighta-bommerz" upgrade. That being said, I'm not entirely opposed to it - I'd just have to find space in the document.
For the Shokk Attack Lance, I strongly suspect that this was removed due to being absurdly complicated to use, as well as the introduction of the zzapp gun (which I believe is the "same" weapon fluff-wise) as a dedicated Ork lance weapon making it less relevant to have as a commander upgrade. I doubt I'm going to reintroduce this one.
The tellyporta seems fine to me, and I suspect might have just been overlooked when all the reshuffling happened. I'll try to find room to add this back in.
Regarding your other question: Yes the zzapp guns should be equal strength/range/arcs as the Imperial ship (in other words, identical profile, but uses the zzapp guns rules). The killcannon thing is my bad - it was brought up in the old discussion for BFG:R, but never fully written out, so I ended up copying it without checking. I am currently fixing both these issues (Nova Cannon should be replaced with R30cm, S6, Front killcannons, just for reference).
