Have you ever used a stealth bomber for a bombing run? First of all, you generally need multiple bombs to destroy anything. And in the case of faction warfare (which is the situation we are discussing), its worse because bombs apply horribly to frigates because of their small size.
Moving on to smartbombs, do you know what the range for the largest smartbomb is? I had to go check. Its a whole 6k. And that’s for battleship sized smart bombs. When you go down to the ones that can be fitted by cruisers, you’re down to 4k radius. Technically, you could fit a large (battleship) sized smartbomb on a cruiser, but it would take up around 90% of your powergrid. For one of them, which means your overall DPS would be much lower than fitting more of the mediums.
Furthermore smartbombs are generally not used in PvP to actually destroy and damage the other ship. Yes, they are used in mass quantities for gate camps; but, that’s much more different than FW PvP. Outside of gate camps, smartbombs are generally used for clearing drones off of your ship. I’m sure there are other purposes; but, I doubt those purposes fit the world of FW PvP very often… if at all.
In short: bombs and smartbombs really aren’t related to this discussion and you’re attempting a red herring argument fallacy here by not staying on the topic of “What legitimate reason would a PvP fit a WCS?”
Here’s where your wrong. And I already explained this. The only downside is not taking a low slot, its also a reduction in targeting range and scan resolution. If you believe reducing scan resolution is not a downside, you clearly haven’t done a lot of PvP. So, I’m gonna open up Pyfa here. With skills to all 5, a Tristan has a scan resolution of 750, meaning it can lock a frigate in about 2.8 seconds. When I put in a WCS 2 (which gives us the least penalties), the scan resolution drops to 450; which increases its lock time on frigates to 4.7 seconds. So, 2 seconds slower on the lock. That’s 2 seconds longer where you are not applying DPS or, in the case of the OP, neuts.
Finally, you still didn’t answer my question: what legitimate reason would a PvPer fit a WCS? Saying they provide “a big benefit” isn’t a legitimate reason for a PvPer to fit one. Mining Laser Upgrades provide a big benefit too; but, I’m not fitting one on any of my PvP ships.
