Melee is OP if you weren't aware. Put heavy armor and a helmet on a melee specialist and laugh in the face of danger. Alternatively if you prefer killbox combat and you can get a grenade, build 1 pillar or wall with a surrounding roof, throw some rocks under the roof and when enemies shelter beside rocks blow up the pillar, roof collapse -OP The more villagers you have, the larger the raids. You can have up to 6 villagers without moving up to medium raids. Wealth management is also something to consider, sell/give valuables and unused statues to ally with surrounding villages. This also lowers your chance of getting raided. Finally if Mechs are causing you problems, buy or make emp weapons, they are stupid weak to them. Hope some of that helps.
