I would argue SD Radiants are still kinda meh. They are not nearly as mobile as everyone expects...
IMO the best use of automated ships isn't even Radiant, it's nice but not that good compared to human capitals.
I found that out the hard way. When I tried NL Radiant, Radiant was sluggish, and I had to save all of my skimmer charges as an escape button or else my Radiant flagship was flanked and wasted. Once I got Systems Expertise, then it became the unholy slippery demon I would expect of it.
I also tried unskilled Remnants against Ordos. They died as easily as human ships. AI cores is what makes Remnants strong.
The main advantage Radiant has over Paragon is missile power, which it pays for by not having Advanced Targeting Core.
It was overpowered at 40 DP, but at 60, it is... balanced.
Glimmer is really good for 5 DP even if you do not use cores on it, and with hardwired alphas it's the best general use frigate in the game by far.
This, along with Wolf's inability to support Pulse Laser and getting outgunned by 4 DP frigates, is why I consider Wolf weak. Glimmer has little difficulty supporting pulse laser and probably other bolt mediums. Wolf needs its stats closer to Glimmer, since other Remnant ships are roughly on par with their competitors (aside from PPT and no crew).
Old Wolf in earlier releases had omni-shield and (with stronger skills) felt more like Glimmer of today.
P.S. The one automated ship that really needs balancing is Guardian. Does AI Guardian even need its infinite missiles, or is it just for stop cheese tactics to wear it down? Also, 40 DP is too low for Guardian. While it does not matter at sleeper ships, it gets annoying in bounties where two Ziggurat-tier ships can get deployed for the price of one.
Also, Derelicts smaller than Rampart. They are too weak. Most do not have enough OP.
