I got -15% bonus defence when not wearing set on my ship.
When I put on Aegis set ( gives +5% bonus defence) my ship has -10% bonus defence.
How can be (-)% bonus? I sent mail to support before and they said they will report it. But after 2-3 maintenance there is I can't see any fix about bonus defence...I know they have busy to do many things,lots a work.I hope they will solve it soon if it is bug.
