There is question which is really bugging me - is your chance/success of getting a particular resource dependent on the profession you have chosen ?
For example, I am a miner and in the new locations I had a chance to find a gem, the chance was 31 % highest depending on the location...would anyone with stonecutter specialization more likely to find it ? Do tanners get a better chance of getting light hides from killing boars or wolfs ?
Also, does your proficiency in your specialization also affect the chance to get those resources (i.e. can tier 2 carpenter get more wood from a location or can he only make higher quality refined wood ? )
