1- Attacking a town on a different island needs blockading (occupying) the port first, so sea battle should
be fought first. Since you can not send land troops until the sea battle is over why do you need more action
2- Defending an occupied town and its port is another issue, here you can send land troop enforcements
while the sea battle is still on since your navy is the defender. So you need AP for your navy and army, here
you will use the action point of your own town or the town probably you have garrison rights with it or completely
a different occupied town.
3- Attacking another town from an occupied town, if it is on the same island, may be you do not need blockading
the port… and if you need for “obvious” reasons then having two separate amounts of AP (X for the land
troops and Y for the navy) will give you more advantage.
4- What happens if you attack simultaneously one town by land and occupy another town’s port from the same
occupied town on the same island?
Despite of these scenarios, I think having more action points still is necessary to carry on with the new battle system.
