It's not just the lack of low level plasma weapons that need to be added to the Romulan faction. High level consoles, Singularity cores etc. need to be added. Unless I missed something I have to go to Memory Alpha just to craft an item for a Romulan character. No good.
The crafting system is obsolete and pointless unless it's for the Aegis set which even then that is mostly just used as a stepping stone until rep or fleet gear.
Between missions, ec away team vendor and the exchange there isn't a reason for crafting at lower levels. They might as well either completely remove crafting or finally give it the reboot it needs, and have only unique and extremely hard to find items be craftable.
