There have been some discussions on the deficiencies of the mining system as it is ATM, and what could be done to improve it. Recently, there even has been something like this for the killing aspect. However, all in all, mining is better suited to let you chat than is fighting, due to the lower frequency of clicking, and also due to the fact that there is no competition for limited resources (ie., spawns), thus less aggression so it can, contrary to killing, even be enjoyable, and might permit some RP.
