3 suggestions. I think....

1) Ectos cost 11k at trader, buys for 8.5k
Ectos cost 12k at trader, buys for 9k.
Is there 500g missing somewhere?
2) Hammers have the slowest swing time. You can't tell me that a
dead sword doesn't weigh more than a hammer and swords are
one handed! The fact that hammers can't be used with shields
sucks. Also, 5-14 damage to mountain trolls is unbelievable.
15^50 & customized should do a MINIMUM of 25.
3) If I ignore someone, why can they still put up trade windows?
EDIT 4) Create a stance for non W/ME that lasts as long as the
recharge time. The resistance stances for ME are just
rediculous.

1)Do you mean that if the price is S/11K B/8.5K - it should be b/12K s/9.5k and b/11.5K s/9K? if that is what you mean, then says who?They are merchants they decide the price.Remember that the prices are effected by players the more players buy or sell the more the price changes.

2)First of GW isnt real life, second a WarHamme DOES weigh more then a sword.
There are swords that are two handed but those dont exist in GW
Hammers do 19-35 max dmg hammers can also knock down.
Swords do 15-22 and cant knockdown , thats where it balances out.

3)Cause the ignore only works on private chat local chat and trade chat :|
Sucks i know, but if you ignore someone you can still see them talk in guild/alliance/allies chat :| Fix this ANET!!
