Missions & Complexes

Well, you have two bad options (assuming you're either up against Minmatar or flying for Minmatar against Angels; it's rather unclear from the very brief post).

First, you can fit the damage-specific option, which would basically entail putting arties on the Abaddon and firing RF Fusion. Maybe even ACs. The problems with this route are that you miss out on your damage bonus, meaning you really need to stack more damage mods. But you're also facing a heavy exp enemy, so you need to tank as well. And if you need fitting mods for arties... well, the problems compound.

Second, you can fit as much damage as humanly possible to try to make up for the high EM/therm resists on your targets. You still have the tank issue, but at least now you're looking at a pulse fit (probably; there is an argument for going beams and being able to deliver more therm at longer range though) that takes advantage of your hull bonus.

Neither is really a winner. If at all possible you might want to look at a NGeddon for this and getting the most out of your drones.

firstly, abaddon for pve: no

secondly, lasers vs angels/minmatar: no

and no t1 armor tank vs angels, its like to tank EM/Thermal with base shields, just shield are more easy

With enough SP the Abaddon isn't actually this bad against angels, assuming you get enough dps, use conflag at close range(higher Thermal damage makes it quite a bit less painful) and faction ammo against BS at med range(scorch is rather bad because of the high EM damage). Anything sub BS that isn't a elite cruiser doesn't have any kind of high EM resists so scorch works fine here.

I generally tend to fit 4 HS(-1 EANM) against angels since they are fairly easy to tank if you can kill them before they come to close and you can't have enough baseline dps to deal with higher EM resist but that might be personal preference. Basically fit omnitank, think about how much EM damage a crystal does, chose accordingly and it is rather easy. Just takes a few minutes longer per mission(AE for example around 40 w/o room 6 compared to around 30 with the optimal ship for it -> mach).
