Given how all the defences currently work, a "general" nerf to Dodge would basically consign ALL defences into the bin other than PRR and HP (as AC matters little when enemies hit you anyway or when they do hit you successfully it's in the 5 digit region), and thus would be highly undesireable a result (general nerf to Dodge).
Currently, SSG needs to take a good hard look at this, because they really only get one chance at this, since it'll be so wide encompassing when done and often they are resistant to changes after spending time on doing such changes.
The decision to push it down to another update is the best decision they could have taken, because quite honestly, given the speed we are getting the last two previews and the increase of content available between each preview. I would imagine that the raids players are interested in may not even be complete at this moment (of preview 3) and with more items to arrive (possibly with new mechanics or logic). So they hardly have the time to make something good of this given the time frame they are working with for U55 release.
There's a LOT I can say over this, but I'd save it for another post or thread.
