This has yet to be the first straight forward feedback topic ever created since I started modding. Good job.
About 50% of this was already listed on my to-do list (%slow skills, early gold abuses, immunity skills, special box rework, etc) (credits to suchbalance), some of this info is useful as I've stopped playing long ago and can't really guess this.
I do disagree with a couple of things such as bashing poison builds because they can easily do K3K - I mean there's not much you can do with poison based builds anyway. The actual problem here is the easy respec system. I also disagree with gift box removal, the problem is in character orb. If people want to waste time farming gift box when they can use early game runewords instead which are much more efficient, let them be. Although maybe 3 uniques is a bit too much. As for cow level, I do intend to rework experience rates in general so that all ubers are exp-worthy. Though there will certainly be an uber that provides more exp than others. And fyi there will always be beggers.
Anyways, moved to sigma subforum. Keep them coming
