During long sailing trips it would be nice
to have some kind of reinc simulator where
I can plan my future in bat

Does it matter who does that? Players get
the same benefit even its done by some
wiz or player and I havent heard slightest
rumour of any player planning to make one.

The problem in a reinc simulator is not really the page that does it, it's the
data.
Wizards might not want to make one since they do not give accurate data out
anyway, so a reinc simulator made by wizards would need to collect the data
from either players or through some random generator.
As a player, I've thought of making one. I've decided not to, since collecting
the data is a real pain in the arse as they might change any day through some
tunes.
Other annoying fact is that races have racial costs that are not known, which
makes datacollecting even more annoying that it would otherwise be.

I would just build one based off of say human race then change with a
multiplyer (aka skill spell race ratio)

say uc at 80 cost 10000exp for human then if it cost 13000 for ent oviusly its
a 130 multilpier.

just a though

As I said earlier, making the thing isn't difficult, maintaining it is.
Racial skillcosts make it necessary to uphold a list of different races
skill/spellcosts, making the simulator require even more work to maintain.
Lets just hope that the one Shura is making will have the wizards backing to
be able to get the data directly from the mud.
