Detail will be depending on your skills, but my first thoughts:
I’d replace the two armour plates with a Damage Control and a Heat Sink. The Damage Control will increase the resistance of your tank (armour and shield) to taking damage. This is good in an absolute sense and because it makes you run the armour repairer less.
The Heat Sink is a simple “more damage from the turrets” module.
Normally you want better resistances for an active (repairer based) tank, and plates and resistance on a buffer (sheer mass of armour) tank.
The change will give you less overall armour, but it will improve your repair rate and firepower.
Try an Afterburner (a 1MN jobbie) and a Cap Recharger in the mid-slots. The MWD is very capacitor demanding and reduces the size of your capacitor. And while it’s running it also makes you a lot easier to hit. Yes, you are fast, but if you are low skilled there’s a lot of downsides to it. You won’t be as fast, but you will be more effective.
A capacitor recharger will give you a lot more benefit during a mission than the relatively small increase a small battery gives - I like batteries on some ships, but in this case you want recharge rate. Keep an eye on the capacitor and don’t let it drop below about 25% - below that the recovery (recharge) really tails off and you end up in a nasty hole. Remember: Standard crystals may do less damage than Multifrequency, but they also consume a lot less capacitor. If you don’t need the punch to kill a frigate…
You’ve not fitted Rigs. They really are worth it. As a suggestion have a look at a combination of:
Explosive Armour Reinforcer (the Kinetic could help as well) to improve the armour’s resistance to damage.
Semiconductor Memory Cell (or a Capacitor Control Circuit) to improve your capacitor performance.
Energy Turret Metastasis Adjuster - this improves the tracking of your weapons to give you a better chance against small fast moving targets. The alternative is a Collision Accelerator to increase the damage output of the turrets.
You get to choose three rigs - play around in the simulation since they aren’t cheap and a destroyed when removed as opposed to modules that are more swappable.
100 dps is going to be a limit on the SoE missions - though the changes above should give you nearer to 120 dps, you can add more with skills. The last mission is the most demanding on firepower and requires at least 100 dps to break Dagan’s defences (he can repair at that rate).
Train up some of the gunnery and engineering skills to make your life easier.
I’m happy to work through a more detailed fit with you - catch up with me in game if you wish - but that should give you a good starting point. The Coercer is a good destroyer, pretty with a good punch to it - going down the dual beam laser route is a good way to start.
Good luck, The SoE arc is a nice series of missions - an interesting introduction to a lot of New Eden and the various factions.
