So far, Wisp seems to be subverting all expectations. Her synergies are synergistic, her powers are powerful...BUT
there's a design that I think was missed out on for her 4.
The sun usually emits solar flares, it's just that with us being SO FAR AWAY, we're rarely ever affected by it...
But in Wisp's case and you know, the fact that she OPENS A PORTAL TO IT I find it hard not to get hit by it.
Basically, much like the Ocucor, with solar flares in mind and the ability it has to spread its presence over a large area, maybe Sol Gate can have a similar function in mind to boost the abilities overall effectiveness against multiple targets. However, unlike the Ocucor, it doesn't have a set mag size and can fire essentially fire forever given your loadout. So perhaps limit the amount of beams to 3 or 5 total.
