What about the option of adding a section for Past History and what is going on in the Present.
I don't have a problem with this, but it will be relevant to my next point.
I personally don't see the point of the description section under appearance as characters can be seen and this is not a text based game and currently use it as a section describing her personality and how she acts around others.
Some people will use the description to provide a level of detail that can't be done with WoW (or any video game conceivable right now). It is a useful field, nothing requires you to fill it in.
In turn, I could argue that the past history field is irrelevant, because other characters can't simply learn your past in passing, without asking your character about it. It really depends on a player's style of play which fields you are going to want to use. I don't think it makes sense to divide the history field into two separate when it would benefit very few people, whereas removing a field that has been available for a while, might annoy users.
We will have to see what the developers think!
In response to
#1: Being able to deactive/activate the two gained channels.
That is not a wise decision. Deactivating the channels will effectively break MRP because it uses them to send/receive data. The only way that could be added is if MRP rerouted all its information through a new method which at this point, IMO, is not needed.
Is such an alternative method for sending information to players available in the API? If so, what are some of the advantages and disadvantages of that method vs. the 2 addon channels that get created?
