Finally managed to clear what I think is all the map zones with a Vampire Warlock. I suspect Wolfengange was pretty thorough in his kills to get to level 25, I finished the emperor at the very end at 24 about 2000xp from leveling. Here's what stuck out in my mind most:

Capital was a joy to stomp through most of the time, I can't wait to smash it into ash and cinder in 0.3. The one thing that slowed the pacing down was that I wanted to reorganize, dump gear and craft sometimes, but finding a location with a workbench, anvil and tailor in nearby proximity for the random grab bag of items I wanted to try to make was a pain so I just didn't bother at the end. Somehow this run I didn't manage to find a tailor tool (scissors) all the way until trading district of the capitol either which was unusual and not an annoyance, but it meant I didn't make a single cloth item on this caster when I otherwise would have even just for fluff. Honestly by that point could probably have ran around naked and still have slaughtered everything although the emperor might would have been risky.

The districts themselves have great character and flow really well. The burned district felt a little bit like an isolated sneak preview but most of them are impressive in the way that they are seamless and don't feel like tile "chunks" on a map, in addition to just the general architecture. Quarantined zone though felt too quiet and had some of the lowest enemy density. My instincts wanted there to be something like a mutant outbreak barely being contained that could be unleashed upon the city by a cunning player or something similarly sinister.

Really enjoy this first arc of long term character goals going like
1)Burst into the world, struggle to survive in a mean place that doesn't care about you

2)Gain foothold and become general menace of the area lurking about the outskirts until

3)Power level growth hits runaway status, now it's time to find the nearest hub of centralized power and commerce to raze to the ground

~Abilities:

While class ability lists are a work in progress, I was wondering if it'd be easy to make it so once you've hit a certain level past 13, the abilities you can choose from cycle around back to unselected abilities from level 1 and progress back up random trees again instead of giving you nothing. For fun and testing's sake? :P 

The other thought I had is that I feel like giving certain skills and spells the capability of casting light temporarily while the animation is active might give them some nice additional visual impact. In 0.3 will buildings on fire cast light similarly? On the gameplay effect side of this I'm coming from Cataclysm DDA and I like most it's system of lighting where creatures outside of your FoV that are illuminated in the darkness can be seen from outside your usual view range. 

~Quality of Life/Misc:

With the +sight gear one accumulates plus my 1600x900 resolution the ability hotbar frequently is obscuring spotted enemies at the south side of the screen. Had a couple of ideas to alleviate the issue

1)Ability to pan the camera a bit directionally, maybe with right click or shift/alt + arrows/wasd?

2)Variable zoom levels

3)Bind a key to force invisibility and non-interaction of hotbar with mouse. Probably my least preferred but guessing the easiest to implement

I thought I saw a bug post on this but now I can't find it. When the inventory screen is on top of "Items Nearby" clicking in the inventory where Items Nearby would be tries to pick up those items.

~0.3 Destruction related:

The first thing I thought of when I ran into an imp in the forest this run was "oh, these are going to be a big problem in not too long". Will there be seasonal environmental effects (rain, snow etc) or other factors that will resist/balance/mitigate some of the destruction happening? I like both the simulated chaos and constrained approach with these things, just curious what direction you're envisioning things will take.

I was also thinking about starting a thread for ideas for new abilities that will be related to the systems you plan to introduce in 0.3 and it'd be awesome to have some more insight into what the scope of that looks like for the sake of coming up with things that are remotely realistic and implementable :P So far what I've got is mostly centered around 'fire' and 'smash' lol.
