Right, here goes....
Mazdamundi:
Powerful but INCREDIBLY expensive at 390slaves cost
Kroak:
Surprisingly reasonable. Stick him in a TG unti and run up the board and spam multiple deliverances he is basically a bomb. 200 slaves only
Kroq Gar and Grymlock
No CoC as troops

but a little stronger than last edition and around 25 slaves cheaper I think. Wardsave on carno!
Tehenhauin:
Meh who cares unless you want swarm spam
Slann:
Casting power took a big hit but theres a ot o customisation options and should still be among the most powerful magic users. Cant decide if I want him with book of ashur or channeling rod or the +d6pd for d3wounds item
Oldblood:
Lost 1init but 5 pts cheaper and pred fighter
NOTE: You WILL need a skink to babysit if you are worried about pursuing
Chakax:
Cheaper but my bets are still garbage
GorRok:
Surprisingly I think he will be very worth taking, eszpecially combined with new sking beast magic. Reasonable price
Skink special chracters look reasonable but dunno if Id use any of them. Much cheaper and more synergy than before. Tiktaqto worth taking in a large terradon unit
Saurus and sking cmbat heroes cheaper. Priests can take beasts
Temple Guard cheaper but more or less the same
Swarms giving poison and cheap but special
CoC could be better but at least better than before
Kroxigor Im happy with the change and might put a few in if I can find the points spare
Terradons have lost hit and run. Being monstrous cavalry does the toughness of the skink get used?
Stegadons cheaper
Bastiladon Im somewhat disappointed with. only 75 slaves but T5

Arc of Sotek gives a d6 range 2d6 s2 hits but not poisoned. Swarm unit gets additional base on 4+ once per turn (can increase beyond start size)
Solar engine is whats been stated before, only the roll of 6 on the damage chart of the beam debuffs the enemy WS and BS. Tail attack is one nominated attack on enemy in rear arc with +1 hit S10
Rippers actually seem pretty decent. Should wreck smaller units and toaded units. Only issue is if we have to use riders toughness (armour save 4+ btw)
Sallies are nerfed a bit but should be still fairly decent. S4 breath is nice.
Razordons look ok to be fair and cheaper points should see some tries of them.
Trogladon is garbage, spit poison is 1 shot per turn only and the models stats are poor. Only decent rule is making predatory fighter on 5+ but only 12 inch range for 1 turn. Rod allows to channel...big wow!
Ancient steg is nicer being cheaper and EotG does all 3 effects every turn although nerfed as stated before. Basically means we can have spears instead of HW on saurus and keep a parry save but only 6 inch range so Im a bit miffed
Blade of Realities says nothing about regen saves...
Sacred stegadon helm can be taken on saurus!
Not sure if I can put it on a scar vet on a carnosaur and have the D3 impact hits at S7
Also does anyone know if the lore of beasts spells that buff characters also affect monsters they are riding? Im sure some of the spells say the MODEL gets +3toughness or attacks or whatever
