The Play Online viewer really loses its necessity after the upgrade to this, except some friend list management options. (I don't think you can delete someone off your friends list, or rename them or any kind of management except add while in game).
This would be a great time to, on the PC and possibly 360 and PS2, remove the play online client and replace it with a stand alone launcher similar to FFXIV. You'd just have to push an update through POL that changes the executable, and archives or deletes the existing launcher, to a simple login prompt (exactly like FFXIVs).
FFXIV for those who don't know, has a simple setup of:
Username
Password
One Time Password
Along with some information, a link to the Lodestone (FFXIVs equivilent of Play Online.com), and a maintenance information page if the servers are down.
The clunky PoL login interface has served its purpose and should be done away with, especially if billing is now going to be handled online. The chat rooms are empty, Tetra Master is offline, services are now going to be removed from it, it's it for except a really drawn-out login box? Even the PS2 version could be updated to a simple login prompt and server information page.
I'd also be in favor of removing Handles and linking it directly to your Square-Enix ID for all characters, which could, in the future, allow for Cross-Game chat between FFXI and FFXIV. (Don't think it's possible? EQ1 and EQ2, and SWG, and Vanguard, and others, support it. In fact you can chat with your guilds in-game from the website, and even from a chat client they made. It's years ahead of POL).
(If this issue is addressed someone I didn't see it, I did a forum search and looked in the article and found no discussion on it).
