To risk going into wishlisting here, I kinda never understood the Iridium armour's limitation, especially when compared to the Artificer Armour upgrade of Space Marines (all flavours that have it and similar). SMs pay the exact same price for the exact same thing, yet have no penalties. This makes even less sense, when most descriptions of Art-Armour only say it looks prettier and older then regular power armour. By that logic, "Pretty Marines" would have 2+ Armour saves across the list. Iridium Armour specifies that it is special improvements to the armour. If I was adding heavier armour to my Battlesuit, I'd request stronger actuators and other moving magubines, so I don't lose any mobility.[/rant]
Looking back onot the rumour posting, I'll give my thoughts.
New Battlesuits will be cool, as I'd use the newer suits on Team Leaders and characters.
The Sky Ray and Fire Warriors Options and buffs sound pretty good, but I hope they cost then approprietly. Can't help but think some die-hard Space Marine player will cry "Cheese" at the Sky Ray "Orbital Blast" ability. I'll probably go for BS4 Fire Warriors, as I often have minimal FWs on the table as is (More a collection restriciton then choice).
The Kroot Creature seems to be having trouble fighting into the list. Being either to easy to kill, or not used all that much, and was/is overcosted.
Interesting to see Kroot gaining Furious Charge, Move through Cover, and 6+ save. If thats for the same price, then they may see more use than just a meatshield for Fire Warriors.
The Battlesuit 2+ Armour sounds to good to be true. I can't help but think it would be a Special Characters added benefit, rather then a standard armywide upgrade, similar to "Veterans of the Long War."
Hmm, either I didn't read it properly, or the Dreadnight does have a 2+ save as standard. I can now somewhat understand Chicops reaction, though still think he was overexagerating its OP nature.
