I would like to mention The MR's training ground is an asset to the world of MD. Having worked in the dojo for quite some time I believe the MR training ground has accomplished more in a matter of weeks than the dojo has in months. The Training Ground aids players in creating rituals and substantially increasing stats in short periods of time. Most importantly players are learning invaluable techniques in creating effective rituals.
I do not agree the Training Grounds are in competition with the dojo. I think they make the dojo obsolete. However more importantly, the dojo and The Training Grounds are two different entities. First of all the Training Grounds are there to teach people as pointed out earlier. The dojo does not teach it is a sanctuary with the ability to duel. As stated "ALL players have the right to one or two locations (dojos) where they can train, set rituals, and do healing rituals free from unwanted attacks." - Calyx of Isis This separates the Training Grounds from the dojo. Therefore I do not think there should be any conflict of each entity existing and existing separately at that.
