Like in the future (Since I know it's not "Officially Supported")? I just tried it to see what it was like (I haven't been able to explore much). While I'm not amazed at the 3D-ness of it, I like the hotkey-drag-and-drop-on-the-fly stuff, the right-click-to-loot, and grid features it has. However a few issues make it hard to play with on Pandora UO (The Pandora Toolbar, Pandora Warps, and Missing Strings on every object). I'd probably play on it if I had a choice between the two clients with the easy hotkey and customizable stuff is why I'm asking. :?
Good possibility. It runs Pandora fine with minimal bugs, and 95% of players prefer classic client.
I run EC sometimes myself on Pandora. I don't believe the loader has been updated on wiki yet and ill let Vorspire know to do so when he has time.
