Have Mithril Coin costs been adjusted for travel in Helm's Deep yet? I have not "re-downloaded" Bullroarer since deleting it before the change was made and it was made available again.
There was no timetable given for a reduction of cost, not even a "soon" but it was described as temporary. If a decision has been made to leave them as is, I'd like to formally request and suggest that MC point costs be reduced now. I think as players bring their 2nd, 3rd, and beyond characters through an area, it's reasonable to allow them to skip unnecessary travel time without having to pay such a steep price, especially since it seems in some cases built in for that purpose (I'm not saying it IS, I'm just saying each time you do nothing but travel between two distant NPCs, it's memorable and frustrating).
I'd also like to see if allowing one free MC travel on a timer similar to the one player "deaths" invokes might be possible. I think it would certainly cause some people to use it more that don't normally and while those that might use it rarely might now get a free travel, it might also "spoil" players who like using it often and get them to use it more, perhaps offsetting the MCs not used in those aforementioned more rare cases.
