Adjustments to repairing:
Do you find yourself having to repair more or less often?
Since I mostly play Operations, I can't really tell because noone is running them on PTS. During the few heroics I did it felt like less often, but then again you don't really die there so it's hard to tell.
When you repair, does the cost increase seem significant or fair?
The increase seems insignificant to ME, but I do have a few bil saved up, but that shouldn't be the main focus. To casual players who are just running some heroics or flashpoints here and there, it could be quite significant in my eyes.
Adjustments to travel:
Do the Quick Travel costs seem fair? Do you think this will affect your usage of Quick Travel?
No, they don't seem fair. Your point with this change is to address the, admittedly bad, economy of the game. All this does is tax beginning players who have very few credits to begin with, leading to them needing to run around a lot more, which in turn probably leads to more new players quitting the game early on, at least in my opinion. It won't affect my usage of quicktravel though, since again, it doesn't really affect the players who have already saved up a bit.
Are there travel costs that you currently find to be too little or too much?
Again, they're fine for ME, but for casual or new players, which probably are your biggest playerbase, they'll probably add up to quite the large amount to them - which in my eyes just hits the players who aren't part of the economy problem.
Are there methods of travel that have no cost that you would expect to have a cost?
Nope, but I think if you really follow through with this, stronghold travel shouldn't have a cost. You already make players pay a rather large amount of credits just to unlock them, and now you want them to pay every single time they want to use what they already bought? Come on, you can do better than that. Some general feedback from me here:
If you really do care about this games economy, which I'm starting to have my doubts in with every new patch you drop, you should aim to tax the people making billions every day by trading wanted old or new items. Add a tax to player trades and mails just like the GTN has, and maybe increase that one too. Add cosmetic credit sinks, just literally ANYTHING that won't negatively affect new or casual players, because all that will do is reduce your already low playerbase even more. If you really do follow through with this form of solution, at least make the cost scale with level, or even make it free for low levels, so it won't have that big of an impact on new players.
TLDR: Not a fan, because this will most likely only affect players who are not part of the economy problem. Sad to say but your patches and patch ideas are getting worse and worse every patch.
