I love it when people bring up mark and recall because:
1. There is only one mark, hence it only works for one location, which I decided to make my house.
2. That means I must be a spellcaster. What if I don't want to be a spellcaster?
Then you drop on into a shop and buy yourself an Amulet of Recall, or Potions of Mark and Recall, or a couple of scrolls. Either that our you resort to the 4 other forms of transportation that the game offered.
The problem, as I see it, is NOT that FT was in the game, but that "normal" transportation that you would expect to see and use, wasn't. IF there were alternatives other than "walking", then FT would have been "optional", and there would have been about 90% less complaints. As it was in OB, with the game written to depend on it, very little of interest in between, and with no viable alternative, it WASN'T "optional", unless you were willing to spend hours of playing time hiking between places that you should have been able to take a boat or carriage between. When there are NO boats or carriages, other than a couple of galleons in the harbor, one of which is permanently moored and converted into an Inn and the other owned by a bunch of pirates, the game world isn't believable. MW had the Silt Strider caravans between towns, boats between ports, Guild Guides available between the various MG locations, Propylon Chambers between the old fortresses, and Mark/Recall sequences or Divine/ALMSIVI Intervention spells to teleport you to specific destinations, all of which fit in with the game world. OB's total absence of transportation facilities, other than the Stables, just felt unnatural.
I don't care if OB's FT system is "in", and I can even recall occasions where it was handy, as long as there's a viable alternative as well.
