I think I have a pretty good idea of the stat ranges for the new greater dragons. All except dex which I didn't pay much attention to because it is too low to make a difference in tamed greater dragons. I also have only included the skills that can be over 100 after taming, and I'm very iffy on the lower ranges of the skills. These are all pretamed stats.
Hit points, strength and dexterity are halved at taming. Wrestling, tactics and resisting spells all lose 28% (X .72) on taming, but will train back up to a maximum of the pretamed skill minus 10% (X .9). Magery loses 10% on taming and that is it's new max. If you want to find out what your skill maximums will be for wrestling, tactics, and resisting spells, right after taming, before you do any training, divide those skills by .8.
Stats:
HP: 1000 - 2000
Str: 1025 - 1425
Int: 475 - 675
Resists:
Phys: 60 - 85
Fire: 60 - 90
Cold: 40 - 55
Poison: 40 - 60
Energy: 50 - 75
Skills:
Wrestling: 115 - 145
Tactics: 110 - 140
Resisting Spells: 110 - 140
Magery: 110 - 140
*********************************
Maximum tamed stats:
700 str, 1000 hp
125 dex, 125 stam
650 int, 650 mana (not 100% on if this is the max for int/mana but this is the most I've seen so far)
Maximum resists:
85/90/60/60/75 (370 total)
Maximum skills:
Wrestle (before taming): 145
Tactics (before taming): 140
Resist (before taming): 140
Magery (before taming): 140
Anatomy, Meditation & Eval are low-50ish before taming.
When you tame Wrestle, Tactics & Resist take 27% or 28% loss but can be trained back up to as if they only lost 10%. Magery takes a 10% loss and stays there. This means the maximum trained skills are:
Wrestle: 130.5
Tactics: 126
Resist: 126
Magery: 126
Anatomy, Meditation & Eval only go up to 100.
This means to get a dragon with over 130 wrestle and 120 in the other skills you would need to tame one that had 144.5 & 133.3 respectively before taming.
