As a poor player (I feel rich if one of my characters gets up to 2 million credits), changes such as introducing quick travel fees and stronghold travel fees seem annoying. I would much prefer, as some people have stated, spending any extra credits I get on "shinies" rather than taxes. What will keep me interested in playing the game for years to come will be decorating my strongholds and obtaining nice looking outfits and pets that no longer seem available via cartel credits.
My vote, therefore, is to make available more stuff that parts of the player base would want to spend huge credits on.
