Out content will always get reworked when new comes around. It is all about the community progressing. Sure my static and I spent forever grinding and learning coil, but that was for those that could challenge new content and spend more than a few hrs a day on the game. Those that can barely spend any time on the game need a way to progress or they get bored, so what do you do? Simple, you let those that were on the "top" end get their shiny gear wear it around "semi" exclusively for a few months, then with an update you change that content since it is no longer "end game" and let us face it 1-5 was never actually meant to be end game, so that those that have limited time can still progress through the game. So when the new coil expansion comes out players that again can dedicate time to it will again be top end with the shiny gear that will again in the future that content will be reworked.
