I really don't see why SCBs are wanted to get a further nerf... and this is coming from someone who does PvP in a Viper already because flying my Anaconda for PvP is already stupid. I've got ~1bil in my Anaconda, and it is totally useless for PvP, certainly way too risky to fly it, since you are target #1, and it's already the case that SCB cooldown is too long and you will still lose shields, even A7, if you are up against decent fitted pilots.
Heat damage is not negligible in comparison to losing hull. It's a big deal. Heat damage will stop you in your tracks nowadays very quickly, it doesn't take much at all to totally break you down. You can probably damage the rest of your SCBs, have your engines and FSD dead... you will just sit there in your big ship as smaller ships continue to eat you alive.
I like my Anaconda for PvE, but there's no question...little ships rule in every respect for PvP unless you want to lose a lot of money.
I can take on most FDLs and below, and win 50% of the time, in my Viper, which costs me 130k to replace. That's the only ship I bother PvP with, and it's a whole lot of fun.
Nerfing SCBs just continues to devalue the big (annies and pys) ships for any sort of PvP at all. Their only value already is either to support in a wing, or to mindlessly blow up NPCs, what a bore.
I hope this isn't taken as a complaint, but rather an attack at the logic. I actually quite like cheap combat, and will continue to do it either way. A Viper, over 100 times cheaper than, say, an FDL, or hundreds of times cheaper than a Python, is a worthy adversary to both of them. Very backwards. I've killed FDLs, Pythons, and Clippers in my baby Viper about 50% of the time, and now it'll be even easier, while I risk 130k and the bigger ships are risking loss of millions. If anything, this will improve my odds of winning and make this even more absurd.
Making combat death in ED for the larger ships easier to happen doesn't make much sense at all. It's the big ships that benefit most from SCB use, and these big ships also already suck for PvP, they can't chase anyone down, but they can run from a losing battle. That's already fair. The big ships are really the only ones that can make use of popping multiple SCB at a time. I can take on 3 A's at a time in my Anaconda. I am able to evade MOST fights, but a wing of 4 has still killed me in my Anaconda popping 3 A's at a time. It really doesn't take long to remove A7 Shields with rail guns already, shorter time than SCB cooldown.
Now you just made it even more of a risk to fly about in any nice ship. Pretty silly IMO.
