You have a point.. 'aquatic'
is one of the most useless rules in Warhammer.
But regeneration... well...
What I'm saying is: You chose very carefully the rules for each religious cult. They're nice rules.
But I have the impression that 'Sigmar','Ulric' and the other Empire gods
are not real like the Chaos gods.
I've red somewhere that Chaos gods are 'creatures from an other dimension, suggesting they posses 'unknown powers', a feature that in the eyes of the people of the old world seems divine . On the other hand, 'Sigmar' is a historical figure who lived many-many years ago and probably....died. People loved him and then declared him 'god'. This doesn't mean they had right(!)
'Hating' enemies is not such a remarkable miracle (it's war after all).. but having 'regenaration', well... that's something!!
If you ask me I would keep these rules
Sigmar - hatred
Manann - Aquatic
Verena - +1 AS
Taal - ignore difficult terrain
Ranald - re-roll failed rolls to wound
I would slightly change these rules
Ulric - frenzy with the official rules that Games Workshop suggests
Morr - cause fear with 'immune to fear' or 'immune to psychology'(Morr is the god of the other life! after all! you know what expects you...or you think you do)
and discard these ones
Myrmidia - ASF
Shallya - regeneration
because I think they're too 'remarkable' for -possibly- fake gods.
That's all and... I think you know more things for the game than I do, though I also like the idea of having more than one 'cult' in the army
(Something that till now GW doesn't seem to share no matter how much we 'argue'
)
-By the way- it's nice that I found your -exclusive- Empire forum, I wanted to share my thoughts and ideas for the specific army, without having to hear for 'rats' and 'lizards'
It's cool
