i think cooldown for crafting is not very good idea, crafting alredy requires big portion of edurance, you have to mine materials then melt into other resources, which are two operations incudling risk, if you will craft some hi tier gear for frend or faction. you will be not able to stay in unguarded locations with advanced workbench for long,
Players who prefer to play non violent PVE way will be sick of this, i used to farm materials for few days and after this i have been crafting for another few whiles, now players are forced to skip between activities, which encourages to use more alt, dual logs and so.
Thanks for another think, devs.
