Not much mentioned here about this but I did some running around with a melee build and 5 points in unforeseen. Its a pretty good addition for melee since you are likely walking around with a shock bone and have 5 points you would otherwise just be spending in something not really necessary. Anyway, its an impressive buff. With 5 points, the hologram can take down alot of trash mob if they are slagged. The range is not great though so you are only going to get melee attackers but I think a low fuse slag singularity or a quasar can work well. Have not tried this out with 10 points as I dont have the spy class mod. Not even sure if there is a +6 unforeseen mod out there but I can see this buff as being you something you can make builds around.
I was waiting to make this build for over 2 years
