I agree with everything you are saying Dingoe and Chac!
The idea of the Heroic 4's throughout all the planets being changed and rolled out was great as this was something that I typically skipped when leveling my main and alts. However I think BW took it's popularity a little too far when creating the Light vs Dark event in thinking that everyone is going to love/want to do everything (and I mean everything) all over again.
I was really excited to hear about the Light vs Dark event coming initially, until the details were revealed.
It just feels more like a "Hey we want to attract new people", or "Looks shiny new content" (not really, just like re-coloured armor in the CM) nothing new for Veterans but feel free to play through the NEW content.
These past 2 weeks are the first time since game launch that I have started to look at other games and play something else.
