Skuttle is next to impossible to use right now. If it has to decloack before it reaches its target, any turret including few offenders or stinger kills it on spot.
1/8 of my skuttle reach its target. Also it does seem to fail to auto-detonate when ordered to attack. I end up self-d when in radius.
I'd suggest increasing its hp to around 500-ish and make it explode as normal when killed.
