So im around the rank of 26 atm and ive gotten to see alot of the Aerlen fixers that dominate the bottom of alot of legions most run a standard Hvy Frig with a crap ton of hull and pumped their points into Tacts and helmsmen taking more energy and hull that anyone has at that rank to bring them down, ive only seen two undefeated one was at 101 kills, and another was at 160 kills both oddly enough Konqul Fixers. the latter undefeated resides in the IoT, and tbh just about every Imperium low rank ship i run into runs a standard 100:1 kdr, no doubt in my mind i could have remained undefeated had i put more rank points into tacts then energy but oh well that wasnt my goal.

But back on topic this rank 26 seemly has unending shields and yet has no shield modules, i know ive tried and looked at his ship, being in a Imperium Legion they are obviously going to be alot stronger then the avg 50:1 Kdr players with more brackets and X-charges. but there is also another way i think that they could have done this, if you purchase 550 GP you can get about 39 x-charge cells and making your shields and additional 200 total shielding 250 minimum now my attack peaks with buffs at 279 which is avg attack of most of the ships in my rank range and to bust through that for me would take 31 shots, which takes 155 energy and at that rank its a good idea that the avg energy is only 100 so to most ships he shields seem never ending and inpenetrable.

Also you cant even peck this guy to death the regular recharge for shields is 2 shields is 2 minutes, and for 5 energy at a 2:45 recharge rate for one energy it takes 13.75 minutes to get 5 energy and in that same amount of time they regain 27.5 shields, so if the avg player is hitting between 8-10 dmg on this guy(thats what i do) they wont even get 2/3 through his ship and his shields are constantly recharging making him impossible to kill at this level unless he gets alerted to a higher ranked legion we may have a candidate to break any previous undefeated streaks that there were before.

To defeat one of these guys, you'd have to out tactical officers, out engineer and out hull these guys with good relays. I was one of these guys at lower ranks and boy was I a tough ship. I'd probably recommend not trying to kill these guys because they are a waste of energy to kill. You want each kill for a red badge to have less hits done each time to be efficient and not auto rank. It is possible since I was able to get perfect syncopated platings and hyperchannel relays by rank 130.

i mean i know already how to beat them, im just discussing the strategy of it.

First off, I'd like to point out that fact that being in an Imperium Legion wouldn't be the best.
It's all a lie when they say 65k drops per day. You're better off at TC or some place that allows you to stay granting 55-80k per day.
It's only because the amount of time invested into freeze ranking which I know you dislike or won't time.
If you check their medal count and find the time they played, it's pretty much twice the amount of mine and yours( the day you reset) combined.
Heck, if I had that much time and stay at Rank 19 for another half a year, I'd be 100+:1 or 100+:0.
But you also have to factor in being zero'd by higher ranks because you disabled/raided/hacked someone at your own rank (only reason why I'm 79:1)

Most of their ships are indeed among the lines of;
Size Class Frigate
Weapons none
Energy none
Sensors none
Hull Protean Armory x3 + Nexus Hull x 5
Shields none
Cloaking none
Defenses Trinity-Core Drive x2

In the end, it's all about time. More time you invest into the SSB, the better invincible SSB you will be.
