http://epicpw.com/helpdeskPvP still occurs daily and there are guilds around that do it
There are daily events and the new content is easy to grasp
Most of the stuff that's new is primal skills, reawakened cards, shards for ornaments and new classes
You'll need approx 1-2 weeks to accomodate to all the new stuff but once you get used to it its same as before
There are new dailies/dungeons available aswell as a difficult dungeon (Forest Ruins) for farming Shards (for ornaments)
Considering that you'll get them for yourself and then keep doing the dungeon daily for Perfect Elements (reshape material, 1:1, you get 10 to 15/ daily depending) you'll be able to upgrade your gears to the new standards quickly
You can also sell the fragments for 10 to 20 epic coins each making getting ECs fairly simple
If you have any question you can post here or make a thread in support, anyhow feel free to ask
