Bashar, the fit you posted does not fill me with confidence. Way too many cap regen modules, which means you have significantly gimped your dps to be able to maintain your tank. The faster you pop the rats, the less time they have to throw damage at your ship, which means you take less damage. More tank does not make the rats pop faster, more tank makes you pop less faster. More dps makes rats pop faster. If you really need that much cap regen to keep your tank from being overwhelmed by NPC dps, are you really ready for those NPC’s?
But let’s take a step back for a moment. You said you want to train your Alpha alt into a Dominix. Why? Because it’s a big tough battleship that has bonuses for drones? Sure, but it’s not the only big tough battleship that has bonuses for drones, and one very important detail is what types of drones are most commonly used on a Dominix? Sentry drones, except Alphas CANNOT train for sentry drones. The most powerful drones an Alpha can train for are heavy drones (and Geckos, which are very expensive for drones), but heavy drones are not a good choice for long range fighting because they are the slowest drones. They take a long time to fly to their target, shoot it, then fly to the next target, shoot it, etc. This is not a good strategy for long range fighting.
So what is a good strategy for using heavy drones? Medium range brawling, with the longest range being maybe 80 km, probably closer to 70 km. Why? Drone flight time. The less distance that heavy drones have to fly to get to their target, the sooner they can shoot it and go to the next target. Also, by reducing your drone flight range, you don’t have to sacrifice as many high slots to drone link augmenters and can fit another turret for a bit more dps.
Now here comes the really crazy talk. Look at the Amarr Armageddon. Another big tough battleship with exactly the same drone bonuses as the Dominix, except fit it with missile launchers, something the Dominix can’t do, specifically Rapid Heavy Missile Launchers. An Alpha with the appropriate missile skills at level 4 should be able to get a shooting range of close to 70 km, you can select any damage type with missiles, something you can’t do with hybrid turrets, and you’ll actually get more dps than the Dominix. The biggest problem with rapid heavy missile launchers is the long reload time on them. It’s really a poor man’s Rattlesnake fitted this way, but you can buy and fully fit an Armageddon for about half the cost of a bare Rattlesnake.
The Dominix and the Armageddon are not exact matches for each other, but for PVE they are quite similar. The Dominix has some advantages, the Armageddon has other advantages. I really think you need to ask yourself an important question before you put a lot of skillpoints into training through Gallente to get to the Dominix. How do you plan to actually fit and use that Dominix, and are there other ships that might actually do the same thing a bit better?
