I suggest all recipies and for all proffesions and mats needed are added to vendors with a price for honor. Its not nessesery by any means but it will be versitile
for example an recipe item that is pve and is equivalent to Whrath Gladiator can cost like 100k honor or some honor and arena rating to avoid bumping undeserved GS if well structured wont harm in any way and even add versatility.
