Right now, you can develop the best armors and weapons extremely fast.

Honestly, who researches things like logistics or training before you have the best weapons and armors?

One soldier with like 30+ attack and defense, will crash any logistics army of trained elite club wielding peasants.

There needs to be a reason to acquire those techs instead of better equipment.

For example, have way more equipment techs with only slight differences, so that getting better equipment would take many breaktroughs.
