Yup... I'm LOVING the xpack beta stuff...
Heres a list of the things I absolutely love about the xpack:

-The Forest: Its beautifully rendered and it just blows my mind away.

-The Music: I LOVE the music that plays in the forest. (one thing I dont like is that animals also trigger combat music, and it gets old that very few steps the music changes)

-Druids: Been waiting almost 6 years for em... Excited.

-Epic Destinies: I cant say but good things about the epic destinies.

-User Interface: Nicely done, clean and cool. (still a bit buggy though, especially HP/SP)

-Enviromental Sounds: Sound very realistic.

-New Audio sliders: We needed to have more options so this change is great.

-Monster Manual: Its not working great, but I cant wait for the full version of it.

In the end, I'm super happy about this xpack. While some people call doom around, I see hope. The Armor and spell changes dont bother me, in fact, I support most of the changes that were done to combat.

Also, DDO looks great, and the forest on Dx11 is just mindblowingly awesome. Especially the grass that moves when you pass through, thats just fun to watch.

I did notice a few things that bothered me... The darkening effect is amazingly cool, but it gets annoying to have the area go dark every time you run into drow, and there are drow almost every few meters. And the astral panthers are way too powerful lol. But those are the only complaints I have.
