i made a little research and i found few troops with traits without sense.
I mean traits name something link. Troops have traits but bonus is pointless.
Marsh raptor, Shocktopus, silver dragon, valkyrii - they dont use blu gems
Falconer, Fire giant, Royal engineer - they dont use red gems
Sun sail, acolyte - they dont use brown gems
Dryad, Leshy, Nymph - they dont use green gems
Bastite priestess, Giant spider, Snowy owl - they dont use purple gems
Anteha - she dont use yellow gems
Is there any chance to fix it and give for these troops any usefull traits?
thx a lot for answer
