I know, i know, high tech ships are great at dismantling slower out of position ships and bursting things down, but not everything can be a Nova.
With enough low/mid tech kinetic dakka you delete high tech shields and without them, those ships are made of paper.
On my current game made a killing developing Tri-tach contacts and farming their high tech bounties. It was incredible how much faster they die.
I have no idea how, or if they could be changed and to be honest, they DO work against slow ships without burn drives/enough speed but at this point, it just feels unfair to bully them. I kinda hope Tri-tach gets a rework at some point.
Good High-Tech ships to use are the TT Brawler, Omen, Tempest, Scarab for average PPT fleets or SO fleets, Hyperion for SO fleets, support Shrike, Medusa, support Apogee for slower fleets, Aurora, support/artillery Odyssey, and Paragon for slower fleets.
Middling High-Tech ships are the Wolf, Shrike, Apogee, Odyssey, and Astral.
The only really bad High-Tech ship is the Fury. It's just way too expensive for what it does.
Most High-Tech ships have a specific niche for how fast your fleet is and how much PPT they'll have. Trying to put a Scarab or Hyperion in a fleet of Paragons is obviously not going to work.
Some are way better in some roles than others. The obvious ships are the Shrike, Apogee, and Odyssey. They're direct fighting capabilities in the hands of the AI aren't great, however they work great when put in a support position. Give the Apogee and Odyssey HILs as Tachyon Lances won't fire if there are friendly ships anywhere nearby.
Due to being reliant on high flux weapons, their shields, and systems, High-Tech ships in general up-front benefit more from officers and s-mods than the other classes of ships.
For faster fleets Auroras will be your mainline brawlers.
For slower fleets, Paragons will be you mainline brawlers.
Tri-Tachyon and their bounties do not have strict fleet setups, which means they get a jumble of mismatched High-Tech ships and weapons. This dramatically decreases their combat effectiveness.
The other factions also suffer from the same issue, but to a lesser extent as pretty much all Low-Tech ships are slow with High PPT, and all midline ships are medium speed with medium PPT. Meaning they work better together.
