Maybe you should actually explain what you mean by 'bridge'. Sending gang link bonuses to another system? No. Just no.

...What's wrong with a command ship?

Just an idea for another POS module to support home defence, instead of having 4 pilots (alts) behind pos shields,boosting only parts of the fleet.

So, you want pos mods to potentially give all gang warfare link boosts to all alliance pilots in a system??

Essentially giving substantial bonus's to the defenders of a system:

without need for fleets...
without the need for intensive training....
without the need for pilots, ships, implants, and mods.....
and
without limits on how many/which gang links are active?????????

and your balancing this with Sov...

What next, a GOD-Mode monocle that gives you unlimited ammo, 99% resists, and siege mode damage boosts?

No..... Noooooooo...... NNNNNNNOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The last thing we need is more off grid boosting.

Current command ships need to be limited to only boosting ships they are on grid with. And if you want more types of boosts, get more command ships with links on grid.

This idea is a step in the wrong direction.

Right, if CCP is going to restrict the boost effect to the grid, this idea is obsolete.

But then they'll have to come up with a decent idea to make the miners happy,
since using the rorqual in deployed mode in a belt is like setting up a "Please kill me"

edit: 5% per level without the need to run the industrial core
instead of 10% per level but having to run the industrial core
would solve that problem from my point of view

From my point of view, this could be an advantage for small corps/alliances defending their space.
Of course big alliances would be able to use it to, but they have enough pilots to run 4 different wings, boosted by T3 cruisers with the corresponding implants.

Except with your proposed idea there would be literally no point in risking high value ships like that in home defense.

Sorry but Command Ships should have to be on the lines fighting. There should be a chance that you lose the bonuses they give. The fact that there is offgrid boosting right now is honestly a mistake and I am fairly certain CCP have said its something they would like to look into.

Why does the rorqual have to be at the belt? Send the Orca for boosting, keep the Rorqual at the POS.

Right, valid point and if CCP changes the range of gang boost to the grid, the idea presented here is, as said, obsolete.
Until then, it might (or might not) be helpful for small corps/alliances defending their space. I assume that you have more experience in 0.0 warfare than me (I'm close to nothing), so you'll be able to better judge the impact of such things.

Well, currently the Rorqual gives 10% bonus to mining foreman links per level when in deployed mode, i.e. being a sitting duck. As long as the range of boost is not affected, this is not a big problem, since you just go into deployed mode behind POS shields. However, when the range of boosts gets reduced to the current grid, instead of the whole system, that bonus is kind of broken.
From a certain point of view, the rorqual should be in the "front line", i.e. in a belt, like the command ships, but it does not work when you're stuck for 5 minutes (sorry, it's 5 not 10 minutes) because you want to make use of that bonus.

Well the first misconception I will address is small corps/alliances. They don't exist in 0.0 space. At least not as separate entities. You need power to hold space and no amount of game mechanics is going to allow a 50 man group or whatever to hold down a couple systems without paying tribute to someone.

Would boosts help them? Sure. Until the swarm of people from an alliance like Test comes in and numbers become the only thing that matter. Sorry but small entities simply cannot exist in 0.0. In reality, this mechanic would only make big entities even stronger and harder to remove as we would constantly have these boosts to help deal with Snigg and other groups that love to roam around 0.0 sov space and the potential invasion force seeking to take our space.
