And presumably this blog will also explain why player feedback was discarded? I'm greatly interested to hear the answer on that one, as I've been following this thread and it sounds to me as though player reaction has been primarily (not completely or unanimously, however) averse to these new icons, while CCP reaction to feedback has been "we don't care." Now if that's not true I'm happy to be proven wrong, but as a rather new player I'm a bit discouraged that this situation with the icons -- something a lot of people have difficulty with -- will seemingly be glossed over with a "this is why we did it" blog post instead of a "we hear your concerns and this is how we'll fix it" post.

The icons are blurry, messy, and make it far more difficult to discern quickly what is in front of me. I too have considered removing the icon tab altogether as not having them, frankly, seems preferable to being bewildered by them. No, I have not scaled my UI to 90% and I still say they are blurry. I play on a 1920 x 1080 resolution screen and daily find myself wishing for the clearness of the old brackets. Instead of mousing over to determine frigate/destroyer, as with the old system, I now find myself mousing over to determine battleship, cruiser, or battlecruiser.
Specifically:
-Battleship icon does not convey a much larger size vessel than a cruiser/battlecruiser icon. I recognise this one may simply be personal opinion but I keep wanting to think the house shap is a battleship and not a cruiser, just because it "feels" like a larger vessel than that rhomboid shape which is the battleship.
-Large Collidable Structure icons are difficult to discern, either in space or in the overview list itself.
-The pod icon, most of the structure icons, and the asteroid icons feel like they are cramming too many lines and pixels into far too small of a space, leaving the impression of a blurry mess to my eyes. I realise that my eyes aren't the clearest 20-20 vision but surely you must understand many people play with less than perfect vision.
-While the drones icons are quite nice, as are the sun and acceleration gate icons, they too suffer from the too many pixels making it seem blurry issue that I have.
-NPCs are NOT easily discerned. I play zoomed out fairly far and when arriving at a gate, I had a rather difficult time telling player battleships apart from the Concord battleships present. Now I know some people will say i merely need to assign colours to players so I can tell them apart from NPCs but really, the previous system of crosses and rectangular brackets worked very well, I do not see why that had to be removed in place of a barely discernible difference as this one is.
-I believe in the case of overview icons that less is more. While it's nice that the various types of drones are differentiated, the various sizes of asteroids and ice are indicated, and we get a new icon for corpses ... I don't see that they were necessary. I only need to know whether it is a drone, not what kind of drone; I only need to know that it's an asteroid, I don't need to know it's size.
-I can see that the old brackets left a lot to be desired in terms of describing what you are looking at. However, the old brackets and pluses and drone xs had this advantage: that they were INSTANTLY discernible. You never had trouble telling apart Concord from player battleships at a gate. You KNEW instantly that it was a drone and not a frigate orbiting you. They were also not blurry to look at.
-for the love of god WHY did you take the triangle icon from the Mobile Tractor Unit and make it the frigate icon? I STILL start wondering why MTUs are shooting at me as soon as I see them on grid and I've been playing daily, which you'd think would be enough time to get used to that particularly nefarious change. If you had to reuse that triangle, could you perhaps have put it on something that wasn't piloted by a player?
-WRECKS. The extra pixels in wrecks are wholly unnecessary. Again, blurry and harder to make out.

I'm sure that's a lot of feedback but I'm really looking forward to reading this blog post. I'm getting cynical already and I'm not nearly old enough to be a bittervet but so far, the response from devs has been so underwhelming that I'm half expecting a post that doesn't address any player concerns at all.

I'd go and shoot the monument in Jita but i can't work out which icon it is
