No it wouldn't. Xp events should be a rare occurrence once a month or something. All the time would ruin it.
One of the biggest issues people had originally, aside from how damn expensive this game is, is how long and tedious it is to level. Around Chapter 3 time it was almost impossible to level to cap without doing a ton of dailies, and that's not including your second class. Thankfully Chapter 4 brought in a new starting zone to get you from 1-50 and everyone's favorite daily, but it also added a third class. So, nothing fixed. Thankfully, they went through all the zones from WC through Limo and upped the XP, however that's too little too late and still doesn't help with your other classes.
They need to go through the original zones and bump up the XP as much as they did the middle zones, because it takes way too long to level new characters. Combine that with the prospect of how much it's going to cost end-game to gear up and you can see why we have a thriving player-base of about 10 people.
Having at least double XP/TP permanently would help a ton and would allow you to level all your classes without a stupid amount of dailies. Oops, but there goes a big chunk of their money. (They still don't get that if they make things more accessible and more easily accessible, they will have more people playing and will be making MORE than they do now; they still have the same mindset as the last company that they have to squeeze as much money out of the remaining players as they can.)
TLDR; something still needs to be done to breathe life into the original 1-50 zones, because as it is there's no new life coming up from the bottom to help fill the gaps or replace people who leave.
