The Imbue pass for U57 was a boost for a lot of ranged builds. Repeaters are among the winners. Even pure 20 repeater has an option to use 1d6 electric spell scaling dice. Access to AA via any elf race for the imbue dice.
The kensei splash becomes obsolete due to wizard levels getting full 1d8 spell scaling ek dice. Rogue levels for another easy 3 dice, 12 arty for expanded clip. 12a/6wiz/2ro
