On the vanishingly small chance Levi isn't a troll (and for the benefit of someone who might think he makes sense), the problem is a vicious circle.
One side has less stuff and has obstacles for entry. So fewer people play it. So you put less money and development in it. So even fewer people play it. Rinse, repeat.
The only way to break that cycle is either give up on the faction altogether or focus most of your energies into growing both factions.
I think the least they could do to help matters is simply let people start as KDF from day 1, at level 25 or whatever they want, and see how much of a braking factor that has been.
It doesn't cost them any significant development time.
Overall, I don't care that much about a few ships. I mean, it's more the insult that they put in all this effort and clearly care this much more about Feds. On a practical level, one or two new ships isn't going to make a big difference, probably.
What really chaps my tuchus is all sorts of minor stuff, like costumes, where it wouldn't cost Cryptic a lot to give KDF more options. (I mean, seriously... mercenary outfit only Fed-wearable?)
while I do not often play as KDF I am inclinded to agree. KDF needs more and stop being ignored for new stuff. Feds need just a competitive edge in PvP. I think perhaps they are trying to stick to the diversity Starfleet has in ships and think that enough of each will show up in a PvP match which doesnt happen.
