Quick travelling through strongholds

The means of quick travelling in SWTOR are many but eachexpansion brings its own modifications to this system making some of them less reasonable to be unlocked.
The most often needed are your personal starship and fleet followed by the capital world and Odessen. And this is when capital worlds strongholds are of great help (even if you're not going to participate in conquests, just to go through class stories).

Legacy unlocks aside from in-game currency (or Cartel coins) require a certain legacy level. The simple math tells us that Personal starship together with Capital world will cost 50 000 + 20 000 = 70 000 credits per each character (you'll need Legacy level 10 for this as well).
Capital world strongholds cost 5 000 credits (50 Cartel coins) each and are opened for all characters on the server. Spending 10 000 credits for both strongholds will give your chars the following quick travel options:

• fleet (no cooldown, works regardless your progress in class story)
• return to your previous location - the one from which you've travelled to the stronghold (no cooldown, works regardless your progress in class story)
• personal starship (no cooldown, you need to unlock your ship first)
• capital world (no cooldown, you need to unlock your ship first)

Travelling is free of charge unless you're trying to teleport  your imp character to Coruscant or a pub to Dromund Kaas. In this case you'll need to pay 1 000 credits. Exit to Coruscant / Dromund Kaas in this case sometimes bugs out allowing invading the opposite faction capital. As of now it seems to work properly, so no Jedi in Dromund Kaas City.
If you do not repeat my mistake and pick the stronghold intro mission on fleet (or your capital world) purchasing the stronghold will grant you a set of useful decorations (mailbox, legacy storage, etc). However, you can pick this mission later, travel to the stronghold and wait for it to trigger.
