No, it isn't a problem - it surely indicates a good deal of confidence in their flying ability - all of my exploration ships have good shields, mainly as I tend to use the surface as a brake on too many occasions!To me this (edit to specity: no shields, weak ship) looks like a you problem.
Edit #2: NPCs are snowflakes, note to FDEVs -> pls make them killing machines so players will start blessing the day they see an hollow square in system.
There isn't - only in the perception of those who prefer to shoot first and chat later (if ever)To me it looks like there is no problem at all.
