Re Zhalo class escort destroyer, its getting better but i would keep playing with it,
my priorities in no particular order would be getting good arcs for weapons, 2 twin main guns mounts, maybe swap the TTs for more smaller ones (without the heavy tubes), etc etc.
the more time you spend (and read etc) the better it will get and its better to have a few good ships rather than lots of easy kitbashes. (not that I really exemplify that
)
