First of all, I think tigers is one of the cheaper guilds to max outside of
dark nerves and vital points which were added to make it so not ridiculously
cheap. Second of all, they get ample transportation services to fulfill the
purpose and daily duties of the guild, so there is no need for anything
further.
Tarken, don't claim things you obviously know nothing about.
First of all, some data (as human):
Tiger to racemax (excluding vital points and dark nerves): 172M
Reaver: 248M
Lord of Chaos (old): 115M
Spider: 128M
Tzarakk: 139M
This is about when reinc sim died on me, but I assume aelana is also cheaper
while priest is more. That puts tiger as one of the more expensive evil
religious guilds.
Secondly:
Lord of Chaos have two feet. They obviously don't need anything more. Or
more relevant, tzarakk has a mount who can cross the entire continent in 10
seconds, yet they get navs. Your logic fails to explain that.
And lastly:
I'm not taking a side on whether we should get navs or not. I'm just pointing
out the irrelevance of Tarken's post.
