These changes will not really modify inflation. For example, about strongholds change... Strongholds are not cheap, neither the decorations. Forcing people to even pay more for just traveling to them, only has 1 single effect, annoy everyone.
I've been on this game for several years and the main issue I've seen with inflation is the absurdly high cost of getting good stuff. Prices on the GTN get higher every year. For example, some armor sets or decorations which some years ago cost less than 400.000 credits, nowadays cost millions.
And there is not really a balance between the income you can earn in a short - medium timeframe of play and the item's cost . This extends to armor sets, packs, decorations, weapons... and almost every item that requires a purchase through Cartel Market, Cartel Market Tokens or some time of old good farming (farming is okay and even fun but in some measure).
I get how a market works and I know the "Law of Supply and Demand". If someone is willing to pay millions for something, why not set such price? I also know that Cartel Market is a way of keeping this game up (in economic real life terms).
Still, I truly believe that If there was an alternative way to get "exclusive" items or others that requires tons of farming, or maybe if there was another way to get cartel coins (apart from some small amount from achievements and security key), inflation would be much lower. Or perhaps, that could be solved by reducing certain "exclusive" items base cost or improving the quallity and variety of quests/reputation items/rewards. If people can get really good stuff from alternative affordable ways, GTN would be less frequented and inflation won't be as crazy as It is.
