Ok, before we start, i did preorder the HD before the beta started. The preorder options were good to have now. Im not sure, i would still preordered had i known exact amount of changes.
Like - the landscape. Its great, and likable, and quests are good.
Big Battles - in current state, they are just a few playthrys, and you have seen all there is. Further repetition highly unlikely. But it contains quite a grind and advancement. It's possble, the devs will add some more things to BB post launch, like more group size variability...
Class changes. Ok, i can understand why it was done, and for a good reasons, but also there's good saying, where roads made from good reasons will lead... The 2:1 penalty and the way one earns these few extra points for trees means, each class will be same single three variation for most of the levelling. Some dipping into other trees will be "point-wise logical" only after you get max out of your primary selected tree, and thats start at about 60+ levels. Also, at least for guard, theres only so much logical way to varie the skills picked in tree, before it goes counterproductive.
My beta guardian is a way stronger that live one. Im also finding myself looking for skills i no more have access to, regardless of what tree i am picking. Buit at least its still almost the same. My LM is for now unrecognizable by me, unfortunately...
