No because you are not giving enough time for people to form up , and move to this system.
People needs time - without this it will be just mindless grind , and waiting for a noobspawn.

If you want to fight - you must give people enough time to form up.


What i missing here is again alliance capitol.
So system where you are getting HUUUUGGGGGEEEEEE boost to your defensive abilities.
Each alliance must have this in order for industry to be appealing.
You need to move tons of stuff to station, and then produce something.
Some production takes longer than time needed that you have for reinforce timers.

My suggestion.
Allow each alliance to erect a capitol.
This system cannot be contested until all systems around it are lost.
Freeport mode on this system is extended by 1 additional day.
Alliance can change capitol only once per 3 months (this timer is reset when all sov belonging to alliance is lost).
System designated to Capitol must have max indexes for 3 days( or maybe more)
All systems around it must be controlled by its own alliance.

1 boosted system, will help a lot for nullsec industry guys , and also make more people feel they are home.
For example.
So lets look on the Brave issue , where their capitol don't have any indexes :

Brave decide that this system will be their capitol , so they dedicate them self and start to grind indexes for this system.
After 2 days and 5000 dead mining atrons they are ready to do it.
Capitol gets erected.

Now they don't have to care about doing any thing in this system.
It is safe as long as systems :
V-3
3-0
AX-
are under their control.
Brave leadership can also think about resetting TEST and taking YHN in order to have additional system shielding their capitol.
