Support - perhaps when you mouse-over a dragon you could get a preview?

Support! I was surprised to find it open another page! :P Its very inconvenient; the original AH's pop-ups were not distracting, good for mobile users, and it gave you all the info you needed at a glance. The images on the AH are already small, so I'd rather not squint to see if thats Alloy or Shimmer without having to open and then close another tab. Although I know that mobile users cant really be catered to, but as one I thought that I would mention that having the dragon open another tab prevents mobile people from seeing the little gene box.

Support whole-heartedly, I especially like the mouse-over version.

I completely support this! I was baffled to find that they intentionally removed this feature. I would really love to see it reimplemented. For me (besides the huge layout), this is the thing I'd like to see reverted/changed most.

I was just coming here to make this suggestion.

I too, was baffled by the removal of this feature.

As many have said, it causes serious problems for mobile users and users with poor connection or slow devices.

Basically I support everything @PPixelNinja216 quoted, too.

so much support. previews were one of the best features in old auction house and i'm very disappointed to see them gone. so useful in checking the dragons - a lot better than having to wait when a new tab loads itself

i don't think that mousing over would work that well, and it wouldn't help mobile users at all. the way previews worked was fast and good, i really don't see why that needed to change

Absolute support. I would love to see this implemented once more. It would make browsing the AH much easier.

Support, tbh I had no idea this existed but it should be implemented back for less clicking.

Support! As someone who has to use their phone pretty frequently, it's really annoying to have to open a new tab. Plus, there's already two other links to the dragon's profile!
