Now that many of the set bonii have been revisited, it would be lovely to be able to craft the +1 exceptional stat of your choice as well as the +2 exceptional stat of your choice, instead of the +1 being set in advance in a way that might not help your build.
For example I'll use Bard sets: Warchanter is the only one that uses +1 exceptional STR. So my Spellsinger uses the Warchanter ring. If the Spellsinger set bonus was more useful, my build would be forced to lose out on +1 STR in favor of the +1 DEX attached to the Spellsinger ring, which is completely useless for her build. Most Spellsingers need +1 CHA or +1 STR (maybe +1 CON in rare builds).
With some epic items being +7, the base +6 is often not useful at all, and is just something you put up with to get the right +1 stat then craft your +2 or healing amp or monky bonus damage on.
Double crafting of TOD ring would allow much better player customization of builds.
Perhaps crafting a +1 stat on your ring could use Medium ingredients and the same recipes, but a Small power shard to reduce the power of the result to +1 instead of +2. (Then also make the Small shard drop from Tower of Despair.)
Is this something others would like to see?
