Ships & Modules

It's not always as simple as 'one is better'. If it was like that, one of them wouldn't be in the game.
Microwarpdrives can be very beneficial, in ships with small native signature radius, or ships with a bonus to radius reduction. However, the bloom can sometimes be a huge issue. Interceptors are a good example, since they can fit microwarpdrives without attaining a gigantic signature radius.
Afterburners give a smaller speed boost, but sometimes have the same net effect, since they don't boost signature radius by a great deal - this means that you can zip along at a slower velocity, but be a smaller target.
All-in-all, it's something to consider on a ship-by-ship basis. There's never one choice that always works.

For tackling, fit both, or if you can only fit one, make it an MWD.

Depends on your ship, tackle is about being fast so MWD when ever possible.

ABs are more for keeping range once you've landed tackle...

Neither is better, or rather, it depends on the situation. As a general rule of a thumb, you'll always miss the one you don't have :p

Personally, I usual prefer to use ABs, except if my ship is "in ur face" configuration (such as Blaster Ferox), if I have a heavy kiter (podla Drake) or if I am a dedicated fast tackler (which also means Warp Disruptor, not Scrambler, because I'm there to prevent the target from running until my team gets there, not to actually keep it slow).

It really boils down to the tracking formula. You've got two factors that determine whether your guns can apply damage (Range and Tracking). Your choice of propulsion determines which side of that game you want to play.

If you're naturally faster than your opponent, a microwarpdrive will let you dictate the range of the engagement. This is a pretty big advantage, especially if you have longer range (lasers) or more damage (blasters) than your opponent. This is probably best exemplified by the Slicer and Deimos, respectively.

But if you've got a particularly small signature radius and are usually slower than other ships in your class (armored cruisers and logistics come to mind), an afterburner can let you win at the tracking game. Better yet, it lets you do so while saving powergrid, capacitor, and CPU. The Guardian is probably the best example of this.

There are exceptions, but it really comes down to the tracking formula and the relative speed of the ships involved. You'll get a feel for which one's preferable as you get more experience.

MWD is for mobility, AB for signature tanking or dictating range in web range. For tackling, always use a MWD

It depends on what do you want to be, a kiter or a brawler.

If you want to kite your opponent, fit a MWD and a warp disruptor(and take care not to fall into scram range due to yo-yo or loop maneuvers) A slicer, LM crow or rail taranis are an example of this (althout the tharanis is usually fit with dual prop)

If you want to get personal, fit an aft, web and scram. (and take care to learn how to do loop and yo-yo maneuvers to reel kiters) Blaster boats and rocket boats usually fit in there.

Also, there are some ships which work with dual prop (taranis, dramiel, some hookbill fits), so you have the advantages of both, without the drawbacks. But your only tank is usually speed. If you get dual webbed, you are history.

For tackle, get a tackling interceptor (ares, stilleto, raptor...) fit a MWD and a long point. fit close range weapons for defence against drones and if you can, fit some kind of extra tank (MSE or tracking disruptors)

I have most of my kills in raptors and crows, so I can assure you the inty way is a fun one.

That is a bad fit, for everything, not just tackling.

Slight bump

Use both.

I use mwd+disruptor for long point.
I also use ab+scrambler for short point and to mess with dumb mwd that get to close.

Do keep your self to one.
