Orges are defo getting a big power boost!
Got myself a small ogre army which I will be expanded soon, I think what Ill be going for is a couple of units of 6 Bulls with FC and iron fists and LA. That gives you the bull charge (maybe), 19 S4 attacks, 3 stomps. The unit is quite tough as well, 18 wounds, 5+ save and a 6+ ward from the new parry rule
My hammer will be a unit of Ironguts lead by a Tyrant. Thinking at least 7 Ironguts (4x2).
Just noticed you can only have up to 16 Ironguts in a unit, which is a shame as 18 of them would be brutal! Tho I guess 16 and two characters would work!
Leadbelchers are also very powerful now, take 5 in a unit and you get anything from 10 -50 Str 4 shots plus they can all attck in combat!
Gnoblars are very important for support. They are cheap and give the ogres rank bouns, make them deep enough and they will almost always be stubbon!
Yhetees are a bit of a mixed bag. Their fast movement and ignore terrain means they can flank quite well, but as they can't break ranks unless you have at least 6 after combat. At 65 points a model I doubt that we will see many huge units of them. On the plus side the new fear rules are really good for yhetees. If a units fails it fear test they will need 6's to hit the yhettees (
WS 1 vs WS4 and aura of frost).
Scraplaunchers are now awesome! The new stone thrower rules coupled with bigger units means these will hit alot of the time. True its only Str 3, but killing blow will make even chaos warriors worry!
Maneaters are not as good as they were. I've seen them used as a one ogre speed bump, there stubbon holding up units. Now with a lot more attacks coming at them I dont think they will last as long
Same goes for the gorger tho these will still make great war machines hunters as they are now!
The slavegiant is still not good, lots of attacks and no stubbon means he won't stick around for long!
Gut magic is again a mixed bag, no more one dice casting if you only have one butcher, so you'll have to roll at least 2 dice but generally you will have more dice to cast with and as all spells are 3+ to cast they will almost always be cast!
Tyrants and Bruisers are still as nasty as ever!
Good luck, may the great Maw smile on you!
