Anyways my thoughts on the imperial knight rumored rules itself... I actually quite like it! The big knock on TCCW's is that you usually have to replace a big boomstick to get one but it seems that with knights they have it bog-standard without the need to get rid of a primary weapon. I still wish I could put a TCCW on my revenant
The I4 is going to be nasty considering most titans are I3 or lower. My poor phantoms are weeping over here. I'd like to see how many attacks it has.
Single its a super heavy walker it will be able to move 12" in the movement phase so it could potentially run down units like wraithknights that bother you. The WK isn't likely to blow you up at I5 if you have full hull points so thats a mighty nice bonus.
The shield itself is damn nifty. Wont protect it from Str D but then again, Knights are a lighter weight battle titan.
Sounds amazingly balanced to me.
