I think the concept of "reboot" did more damage than the change. Had LoS been set in the classic canon, I think it would've been easier to swallow as a sequel.
I am afraid, that if LOS (as it is now) was set in the old canon, fans went mad with rage because it would be very different from old canon atmosphere and style. Since it is separate continuty it is easier to stomach that it is very different from the past Castlevania. At least for me.
It is just a Castlevania game on its own without ties to anything, so to speak. Also, since I am not big fan of latest IGA's entries in the series, I don't appreciate the possibility of LOS using story elements established during IGA's tenure over the series. And besides, LOS would be very limited to what it could do with the story, without retconing whole amount of different stuff, effectively ruining old canon. Given that it would be much easier to create a separate storyline / universe, rather than go through the effort of changing already established stuff, I personally think that LOS did a right thing, when it is tried to separate iself form the old timeline.
Not too fond of the Respect system myself. because then the people with unpopular opinions, be they valid or not, have a huge negative rep.
I think some people abuse rep. system just to vote against people who they dislike, rather than "wrong / bad" opinions. I don't think that is the right aproach to the forum business.
