Moving towards being prepared for the Diablo 3 2.1 Leaderboard & Season Patch to be released, I decided it was time to salvage a few items, which I included Screenshots of.
I am not sure how much of a concern inventory space will be a month into the 2.1 patch but I assume that anything more than spring cleaning is unnecessary. Season heroes will have a separate inventory from non-season heroes [just like softcore and hardcore heroes]. When the first season ends, all the first season heroes will be shifted to non-season [where all our current heroes will be when 2.1 launches]. I would assume there would be some combining or condensing of stashes at that point in the distant future.
