Ok... well starting off there are a few things im not too fond of from the BFG-R
Zzapp guns... :/ these offer the oppertunity to bring much needed lance type weapons to the Ork fleet while maintaining their origins but the blast marker is a silly rule on a fleet that features so few shields and they are not on the Kill Kroozer.
The Kill Kroozer. There needs to be a reason to field this instead of the Terror and its something that has been missing from day one. The price is attractive but the Terror isnt that far off, adding a lance type option to the ship would go a long way towards acheiving that goal.
Soopa Engines. Great in concept but its got poor execution. A simple 5pt (escort) or 25pt (Kroozer+) option would be much better. The weapons idea could work but it must be made standard through out the different ships.
Warlords: Great options here the Freeboota and Mek options add decent options Warboss must maintain the doubled boarding value! the +2 option from Ork Clans is crap.
Warlord upgrades: Some of these should be standard options for ships, there are a few options from the Ork Clans that should be added in.
Ok Ork Clans PDF
Escort Squadrons: Return the ability to take "Lotz" skwadrons exceeding 6, a max of 10 min 12 would be ideal. Retain the +1 leadership for squadrons of 6+ ships. Do not retain the free ship for squadrons with leadership 5 or 6.
Clan rules: wow these are overpowered when used in conjuction with "lotz" squadrons, 10 Ravagers with looted torps for +30 points O_O is just one example. There are some posabilities for use with Warlods only but it seems like a bit of an over complication.
Grubbins: There are some good items in here and they should be looked at for addition.
More Grubbin: More good items, Assault Carrier, Klaws, and Shock Lance are all fun fluffy options.
Ships:
Certain Items should be a generic option for ships such as Extra Turrets, Extra Powerfields, Ram prow.
Soopa Engines should either be a purchased item or standardized as an upgrade in exchange for weapons.
Kill Kroozer: Should have the option to take a lance type weapons such as the Zzapp.
Terror: Should have 2 turrets standard as per the Kill Kroozer.
Grunt: add the option to add Klaws for +5 pts each from Ork Clans.
Rok: Soopa Engines make no sense on this ship, Launch bays are iffy, Zzapp maybe??
Something needs to be done with Heavy Gunz, its disgusting that these are the go to for replacement.
