I've noticed.. units are really nice.. but even with their hp in the .5m range they get a bit squishy.
what they really need is more armor, not hp..
I have come up with a few ways this could be implemented.. some more balanced than others
- There is a unit HP upgrade in the upgrade centre.. just add a armor upgrade next to it.
- Armor is more powerful than hp i feel so it should be quite a bit more expensive.
- for endgame goodness should scale to comparable effect with wall armor (but since walls take 2k wood each and units are cheap this upgrade should be very expensive)
- Add a hero aura that gives surrounding units 1-20% of the heroes armor bonus.
this i especially like because it is not OP yet scales effortlessly in time.(kind of depends on hero toming but it takes a lot of expensive tomes to get armor and only a small % ends up as the bonus)
