I'm glad spellements are being made easier to obtain. At first they were, frankly, a nightmare. I think we can still do some tweaking though. This may be a stretch to suggest, but I think it'd be even more helpful if we had an NPC that we can go to to trade spellements for ones of equal value (like, say, trading a Leprechaun for a Ghoul spellement).
Not everyone plans/wants to have multiple wizards of different schools. I know personally Death will always be my favorite and what I play the most. In that case, getting a Sunbird or Nature's Wrath from a Silver Chest just goes straight to my shared bank to sit there.
I don't mind some spells not being accessible via this method (like Ship of Fools or Deer Knight, though that would be nice) but I think the spells we get by leveling should be more readily available. I know that spellements aren't necessary by any means to do any content, but the sense of reward getting one still means something. It'd definitely cushion the disappointment finishing a Silver Chest puzzle or farming a Boss knowing that what we don't want, we can trade for what we do.
