Let me begin by saying I really enjoy the addition of guild member/officer/leader status to the game. It has long been present in other MMOs and it was due for addition here. The inclusion of that information is something that will improve gameplay.
However, putting in the guild tag is a bit sloppy. Firstly, it makes all the floating names much larger and obscures more of the picture. Secondly, by having it appear before the guild name its extra words I have to read, which makes it harder for your eyes to pick out information with a glance, now theres more to sift through. Thirdly, its not something most people will care about straight off and so doesnt need to be presented up front. All in all, it clutters up the game screen, makes it harder to read guild tags, and presents information immediately that is typically not needed immediately.
For these reasons, I suggest changing that information to the Inspect window. Where it has name, class, guild, just put a line for "guild status" or "guild standing" and add it there. Or even include it on the guild line, same way it is in the tag now but just in the inspect window instead.
This will clear up the playing screen, and again let guild tags be picked out with a simple glance and no extra words to skim passed. Also, it makes the information readily available at the touch of a button for anyone who needs it; most commonly people inquiring about a guild or an issue with a guild can quickly determine a senior member to speak with. Its not something that needs to be spammed in the face of all players all the time.
Again, its an addition I greatly appreciate, but feel a slightly different implementation will make the game look more polished and professional and increase ease of play for everyone. Cheers.
