You know what, whilst I personally don't roll that way, and only keep stuff I think I can use (many years ago I idiotically kept caster gloves on my barb as I didn't realise raid loot was BTC - duh! lesson learned), I do understand and sympathise with this position. It would likely only take an instance of finding out I needed something I'd already given away to change my attitude, as I wouldn't want to feel that regret again. I doubt that I'd be alone in that. Others may well want to avoid that pre-emptively. Sadly that is perfectly understandable.
It's not greed but fear of regret that will drive these behaviours. You can't blame players for reacting in a natural way to such stimulus.
Devs please take note. My conspiracy theory is you're not thinking this through, and that delivering "something" on augments as part of the expansion due to not delivering on ED changes, is pressuring you into hasty decisions on implementing this. I'd prefer you take your time to get a better cost/value balance here.
