Swain W

So basically i've been playing an increasing amount of Swain support, and something that I have noticed is that whenever I 'W' an adc with a yuumi attached to them, I only get 1 soul when technically I should be getting two as they're both in the radius of swains 'W'. I know that yuumi is supposed to be untargetable while she is attached to another champ, but I reckon in this case it would make more sense to be able to get a soul [sg-syndra] .
