i had no problem with pathfinding. maby some clarification on how this drive is working is needed:
the accelerator gates will accelerate the cubes to max speed when they pass through, after this, the cube will start to slow down slowly down to 0.75. this is why loa will build gates within a distance of 5 lj between systems. however, after 5 lj the speed of the cube will *not* yet have dropped to 0.75.
so, if you have a gate at one system, it is well possible that the fastest route to another system indeed is the direct route, even if there is no additional gate enroute and the cube will slow down significantly during the travle.
if its faster to use an alternative route with more gates, the cube will take this way.
as for the costs of the ships, remember that loa never have to scrap any ship... all your ships will always be up to date, and you can use them for any task without the need to build support ships.
its true the loas *income* expands very slowly at game start. mostly because the population grow is realy slow, and linked to the tax rate (more taxes, less grow).
this will leave trade as the best option to increase income during the early game - but loa frighters cost roughly 3 times as much as frighters of other races. loa players indeed have to be very careful what they spend money on.
on the other hand, loa will never pay upkeep for colonies with bad living conditions - they just can colonize every planet they find without bothering about develpement costs. if this is exploited right, a loa player will see a massive income increase once the new colonies start to generate income.
i think loa are extremely fun, and proalby will become my favorite race to play. however, right now there is an annoying bug with will will always spawn loa ships at the default position, regardless where the fleet is placed within the battle manager. this makes defense against random encounters or invaders extremely difficult. i suggest to wait for another patch before realy plaing this race.
