Problem with us engies is that we want to help people.
I can't see us getting any buffs to help others (all the useable buffs are taken) so we look at trade skills as our saviour.
We don't like to see prof only trade skills (prefer a skill based system) but anything in this line to help us help others would improve the traders even more than us. (we have no skills that will be higher than those of a trader)
The only way I see this could be solved are engie only gadgets that reduce the amount of trade skills needed to create items, or increase the trade skills.
It FC want to give traders items they would be the best at creating they just add psychology into the requirements (name an engie with high psy)
Remember traders get wangles to help others (they are still needed after the OE patch, don't tell me otherwise) and ransacks to help them.
They may not have a bot but they do have the nanos that help in combat, and heals even if they are a little pants.
Who do traders ever need to go to to help them?
