GNOME makes often changes without long term strategy or asking their actual users. The removal of Type-Ahead-Find in Nautilus or background-transparency in GNOME-Terminal where mistakes. On the other hand new applications like Documents or Console required resources but provide no benefit over it counterparts. That said - Nautilus improved a lot in recent years and there are even patches available for Type-Ahead-Find (or Navigation). Same for background-transparency in the GNOME-Terminal. The separated top-bar-menus were also a problem (decoupling menus from application-windows was copied from Apple) but now reverted, they learn.
If the design team is aware of the usage and has a plan things fit well! The overview is great for keyboard and mouse users, the dash make simple things simple, they got rid of the useless desktop-metapher (copied from Win95) and also the system-tray (another thing from Win95). The keyboard focused use of GNOME is use core-feature, fast for experienced users and a relieve for novice users. The GNOME-Shell provided a good UI and removed many questionable ideas of the past.

Decouple the release cycle of most applications from GNOME, excepting Nautilus and Settings. There is no need to couple Epiphany, Terminal, Maps, Calendar and so. Evolution already skips every second release. And feature-removal should require a good reasoning and not just „I don’t need that myself“. Many options are bewildering, many forks without merges are worse (lost developers and lost users).
