Concise description:
Modify the existing parachute fortification setting to allow fortifications between territories where a possible chained fortification could occur.
Specifics/Details:
Currently, parachute fortifications allow one to fort between any two owned territories on the map regardless of the map requirements. For most of the maps on this site, there is no problem. But for some of the more complicated maps, it results in some serious unintended consequences. A fair number of maps have been developed with bombard-only territories (usually as killer neutrals). The maps were designed with the intention that a player would have to carefully decide how many troops to advance to that spot since he can never get them back out and they could only be used to bombard other territories.
A good example of this is the catapults and trebuchets in King's Court 2. The catapults are designed with a +2 autodeploy and are designed to only bombard nearby territories and hit the trebuchets. One of the start locations has two catapults, while all the rest have only one. This was balanced during the map development because that start location doesn't have the same access to village bonuses that some of the others do, and the catapult autodeploys can only be used to bombard. With parachute fortifications, the catapults become an endless supply of troops that can be used anywhere, countermanding the original design goals of the map and resulting in the House Hareth start location becoming unbalanced compared to the others.
An easy fix for this situation is to add a simple check to the fortification possibilities: If the given player controlled every single territory on the map, could he execute a chained fort from territory A to territory B? If so, a parachute fort is possible between the two territories. If territory A cannot be forted off of with the other fortification settings, is also cannot be forted off of with parachute settings.
How this will benefit the site and/or other comments:
This change will allow the parachute setting to be consistent with the goals of map designers and with the text notes on the maps. It will make it tougher for experienced parachute players to surprise and take advantage of other players that have long experience with certain maps under conventional fortification settings. I suspect a change of this sort would also be necessary before this setting could start to be accepted in clan war play.
