Reading over the golem changes,not excited. Not even sure if they are buffs...
In addition to no attrition...getting around a...
50% dps increase from the armored is not worth 100% increased repair costs (it tanks damage, increased repair directly nerfs this)
100% increased health for 100% increased cost (with infinite range, they shouldn't be hit at all. This would be fine if they were not niche-ish)
...
but then senses prevailed, and the rest seem fine. So what do I suggest?
If you double the cost of armored, increase health by a small amount (20%)? It is it's job, but sometime even its health is not enough.
For the artillry golem, decrease its reload speed by a very small amount in return for double the cost.
