The Atron is the poor man's Interceptor. It can be fitted for extreme speeds extremely cheaply, with its only downsides coming as a result.
With two midslots, fitting an atron for pvp comes down to a single question: which do I want more for pvp, a stasis webifier or a warp scrambler? most pilots will prefer the scrambler or disruptor, however, webs can appear, especially if there are more than one frigate.
The Atron is not a terribly effective ship for anything except holding a single target in pvp combat for other members of a fleet to destroy, and it is only good at that because of its speed.
A single Atron is an extremely cheap ship, with fittings often costing as much or more than the ship's value, even if they are simple tech 1 variants. This means that almost any player can afford to maintain a large supply of them for fleet combat.
