Rayaghuma, that fit is overpriced, overtanked, pointless, and a gank magnet.
First, very few people will ever gank a T2-fitted Rattlesnake, and those that want to will most likely not bring enough DPS to cut through a regularly-tanked RS before Concord arrives (because those that want to gank a T2 RS may not be the sharpest knife in the drawer if you know what I mean), because a regular T2 fitted RS is simply not worth the time for tear collectors. However, and I hope you’ve posted this fit with your alt, you just outed yourself as someone who flies an RS in the billions upon billions of isk.
Second, you misunderstand passive shield tanking. If you’re making it through L4 missions at 75% shield with that fit, you’re doing it wrong. Peak passive recharge rate is around 33%, meaning at 33% your shields will be recharging at the fastest rate possible. At any other point, you’re wasting passive shield modules where you could be using other modules to, say, apply some of that DPS to your targets. Your entire low rack is completely wasted where you could put in some damage mods to increase the damage output of both your drones and your missiles.
Speaking of drones and missiles, why would you use CN missile launchers? You will get either more damage or better application moving to T2 launchers with appropriate ammo. That is a pointless waste of isk. As for your drones, you don’t need 2 geckos unless you are planning on losing an 80mil isk drone every now and then… you should probably keep better watch on your drones if that’s the case. Also, you want light scout drones to take out smaller NPCs. You would also want sentry drones because the RS gets a bonus to sentries. And finally, in the time you could cut from your missions by increasing both your damage output and application, you could actually come back to the pocket and salvage the wrecks in the same amount of time that it would take you to just run a mission in your fit.
And then your mids… unless you are planning on getting some serious neuting, you should use active hardeners because you get better bonuses. No mission will be able to rid you of your cap before you take out the neuting NPC, and gankers likewise won’t be able to rid you of your cap before Concord shows up. So you don’t need the amps, and the deadspace modules again are a waste when something far cheaper will get the job done. You should have a propulsion module of some sort as well, and some damage application mods perhaps.
You will never ever be able to do enough missions in this fit to be able to make the isk back that you spent on it. It is a complete waste of time, energy and resources, and as opposed to protecting you from ganks, it could actually end up costing you your hard earned isk.
I really hope this is an EFT warrior fit, and you don’t actually fly it.
As far as the incursions go, you can’t even solo an incursion worth doing in that fit, and typically incursions are gang affairs anyways. There are tons of corps and alliances that spend their time pursuing incursions; instead of wasting all of your money, just join with them and use one of their many recommended (and far far cheaper) fits.
As far as wanting to have the best possible tank regardless of cost, first off, you noted that you could spend another 38 billion to get a better tank, so unless you actually have spent that 38 billion and do fly the shield boosted version that you alluded to, you are not putting your money where your mouth is and your logic for having this linked fit is out the window. Second of all, as noted above, if you are that paranoid about dying in a mission with an RS, up your skills. I mean, again, your logic is out the window because with the amount spent on that fit, you could fit up several T2 Rattlesnakes, or you could up your skills to the point where you could use T2 mods and still not have to worry about dying in missions.
I mean, seriously… wtf??? This has to be a troll. You can’t possibly fly this
