well, i would like a tower too, but considering the problems with covering the visible land and problems with the view from the tower (you will see far orth, but south just the tower foundations), this is somewhat unlikly, at least in the near future.
i say for extra level, such as a tower, after say 3 levels, there is a heavey fee extra to pay moremore levels.
we should some depoes all over teh map- for now. like one nead teh desert, near the skeletons, so on and so forth. shouldnt be too hard.
as i said: its not a point of payment but of practicability.
if you cant see half the map, because it is overlayed with a tower, its pretty senseless. maybe bror will be able to implement, that upper levels wont show if you are beneath them, but most likely not in the near future.
and depots about everywhere are not there for a simple reason:
it would be illogical and senseless and thus wont come to pass. or did the fellowship of the ring have a depot at the gates of moria, and another at the bridge of kazad'dom and yet another one at the rauros-falls??
ok, i get it, but then wouldnt the same aply for teh extra crosses? if we leave teh crosses, ther should be a depo near them, no were else. but tas you said from lord of the rings, tehy didnt have depoes everywere, but nore revival places. so the same conflict
