Because most of the discussion in this thread is around a few specific ideas with only a little regarding the class as a whole.
Just wondering why you had bothered to hunt down and necro a month old thread instead of making your own.
The only way you’re going to get the average AF going at those kind of velocities with an Afterburner equipped is if you blow it up. Then maybe some bits of the ship will hit 1800m/s. A Wolf with an A-type AB and a full low rack of Republic Fleet Overdrive Injectors goes at 1511m/s and that’s one of the faster AFs.
You might get that up to 1800 with Quafe and implants, but the fit is already pretty massively impractical.
You’re still going to be running smack into the general issue with AB fits though, which is that you can’t actually catch anything with a MWD unless you dual prop or they get close to you, and even if you dual prop you still can’t catch anything with an MWD because you’re sitting in one of the worst base-speed ships in the game for your faction.
Again, see above for why that still doesn’t work. A 75% bonus to AB speed doesn’t get you anywhere near an MWD on the same hull let alone on something faster, and as I outlined in my previous post there are better options for Heavy Tackle. AFs have traditionally been solo and small fleet boats, trying to make them good Heavy Tackle is kinda missing the point. There are plenty of options for Heavy Tackle that will either live longer or be more cost effective, or both.
And why, exactly, do you think that so many T3D fits run MWDs when 3 out of 4 of them can run ABs? Because in small ship combat an MWD is just vastly more useful. You seem to be both vastly over-estimating the effectiveness of this hypothetical AB fit and vastly over-estimating the effectiveness of the average AF’s sig radius compared to a T3D.
That number is magic then, because there’s a pretty decent spread of both Inty speeds and fits. On top of that you’ve crossed your streams here since the comment about combinations of traits was in response to your second idea, but you’ve gone and brought the magic 2000m/s from the first part into it.
Oh and on top of that you seem to be massively overestimating the speed of AFs as they currently stand, or under estimating the speed of Interceptors, considering an AB fitted AF fit for speed and nothing else isn’t even going to get to within 2km/s of an Inty with just a T2 MWD, and a 75% bonus is not going to make an AF fast enough to catch an actually fitted Inty.
It’s a bonus that’s been on half the T3 ships in the game, and it’s not unreasonable to put it on a hypothetical T3F, unless you just literally meant take the T3D modes and put them on the T3Fs in which case my questions are: “What’s the point in that?” and “What on earth makes you think CCP would do something that pointlessly boring?”
The problem with AB speed bonuses is the same one that’s kept the Sansha Frigate and Cruiser pretty firmly under-used.
If they’re strong enough to be remotely competitive with a MWD fit for solo and small gang work then they’re OP because you can tank ridiculously well with just your AB. If you nerf them down so that the tank is sane then the speed isn’t enough to actually catch anything that’s MWD fitted.
Now that Nevyn has mentioned it I do vaguely recall them trying an AB bonus briefly during the iteration on AFs, but I honestly can’t recall which values specifically they tried but I want to say it was a 100-200% bonus. See above for why that didn’t work.
