Fleet Order - MOVE and BLOCKADE ?

I think it useless, when fleet will arrive to system sitiation may be changed and blockade will be senseless. It's better to make such decisions per turn.

this is for when you've got your fleet and the enemy converging on the same node. To eliminate real time click reflex in a single player turn based game. Give this order - next time you catch the enemy fleet before it runs away because the AI 'clicked' faster than you .. (this would also help with the intercept type of quests) .. 

it is not wasteful in any way since blockading DOESN'T CONSUME AN ACTION. you can turn in on and off as many times you want during a turn.

Sounds like a great idea, and indeed it can become troublesome when the order of execution for the AI's actions leads to ships 'slipping by' just because the player was not 'quick enough'.

What if this wouldn't require an activated action but rather an action icon that could be toggled on and off per fleet? Once this behaviour is toggled on, the fleet would automatically blockade upon reaching its destination.
