Interesting, since I wasn't planning on shelling out $35 a pop for an 18-point unit. The one Lobba I have now is a converted Leman Russ part. I don't remember which variant uses the giant barrel, but it comes in the Punisher kit and rarely gets used... An IG player might have a couple lying around.
I've never had an opponent get weird about using slightly different models. Try out, 1 or a few. A was sold on them when I first fielded them and over the course of 3 turns killed 3 reapers (2 in one turn). Not bad for 18pts.
How about Grotsnik? Is he usable in place of a Painboy and a Nob?
I've not used him extensively but he performed ok when I did, not exceptionally. If you're rolling nob + painboy together into grotsnik then its an eggs into one basket case, something I avoid with orks. It does give fearless though which is nice but if I'm taking 4 painboyz and 4 mobs of boyz then I take 2 ork horde detachments giving me 6 of each slot to play with. That means I can easily add a warboss with eavy armour and
PK or bigchoppa if you want to skimp on points. Gives the mob
ld 9 and a bit more bite. I personally prefer this but I'm sure you will get some decent milage out of grotsnik.
I ask mainly because I have the model and can't seem to find too many different Painboy minis. I have the older resin one and I should probably shell out for the new plastic one, but aside from that are there any other poses? One of the cardinal sins of an Ork army, imo, would be to have 2 identical HQs.
I use the new plastic one,
GW do 2 more models I think. I went with spellcrow and got their one and the painboy upgrade sprue converting a nob as another. For the fourth I use my brotehrs. He has converted 30 'nurgle orks' which look awesome. I use his nurgle
PB with is a plaguebringer conversion but I'll probably grab one of the other
GW models at some point.
I like to keep
Manz missiles, trukk with ram and 3 barebones meganobz. For me they are a distraction, one that often actually does well though. If they can soak a turn of shooting and die, they've completed their purpose, never lost them all in one turn though (only played 5-6 games with them so far)
