Air Burst IOs won't convert by category

[FrauleinMental]

When converting IOs, those from the Air Burst set will not allow the set category (Ranged AoE) to be selected, only in-set or by rarity.  The only option in the drop-down menu (for out-of-set) is by rarity.

I know that this has come up before, and the upshot appears to be that conversion to other sets is determined by what other sets are available at the lowest end of the set range, and Air Burst is a 10-50 set, and is the only Ranged AoE Damage set at level 10, so there's no 'in type' conversion available for it, and the 'by rarity' conversion will be limited to whatever sets are also available at level 10.

Ok, thanks.  That's probably what it is.  I had to do roundabout conversions to 'by rarity' and then get what I wanted.
