Sure you will get some complaints about not having woe available now, but it won't be nearly as big of the complaints about the unbalanced and one sided fights that are going on in increasingly emptier forts with each passing woe.
GM's you failed miserably on giving the gamers adequate time to adjust to the game before dumping woe back into the picture. First gigantic failure was limiting testing to those that could/would pay you for it. Dumping renewal with couple weeks to test out builds on a slow leveling server and resets hasn't made the VAST majority much more comfortable than they were 1 week ago with making final build decisions and leveling strategies. But you would already know this if more than a handful of people tested renewal before you launched it.
You want this game to succeed and community become happy again? Here's how you will do it.
1) Make a real test server for the community to use freely.
2) Cancel woe for the next month.
3) Continue to encourage leveling with spawns and exp events etc.
4) Look into making max guild capacities smaller to accommodate the smaller population of your servers. Not making the woe world smaller to accommodate the larger guilds.
These things won't completely save RO from the erosion that it's suffering currently, but they will definitely put you back on the right track.
