I think that would've worked if it was there on release - while SAO games do have legs, most of the sales are frontloaded, so I can't see the effect on sales from now on being huge. Especially since you probably wouldn't know about it if you're just an average SAO fan who isn't all over 2ch/wikis.Id like to imagine if they get enough complaints so that it potentially will effect sales or mess with their ratings on online retailers then they will start to revert other stuff that was considered stupid by the internet. Or at least we can "hope" for that to happen...
Anyway, I can see some of the changes being removed (buffs on enemies), but for the other ones, I feel like the balance now is better than before. Like I mentioned before, you can no longer destroy a monster twice/three times your level by chaining 2-3 skills over and over, but with NPC allies no longer being useless, those fights feel much better now in my opinion.
