I disagree, at least for me. Generally speaking, taking a speeder directly to the next area means that you're missing 1+ quest (which is usually quick xp). The quick travel cd reduction is a convenience, but it was already low enough for me with legacy. Additionally, you still need that area of the map open for you to QT there, so it's really only a huge convenience for people that haven't figured out the quest pathing or those rare instances that require you to go way out of the way for a quick turn-in. Don't we get commendation changes from the fact we have 12x XP to ensure that people have acceptable gear?
I'm one of those people that spends far too much money on f2p games. I started a subscribing again just before 12x, and probably would have stopped again already if it wasn't for 12x. Is 12x needed? No. Does it generate additional revenue for them? Absolutely. Will I stick around after 12x? I don't know.
PS: I just previewed this post, and have to laugh at my signature. It's interesting how time flies.
