Although I'm far from being able to buy a Dreadnought capital ship, my corp has an extra Phoenix looking for a pilot and I've promised my Director that I would train for it. So in order to properly pilot the Phoenix with Citadel torpedoes and Siege mode I need to train the following skills:
Caldari Dreadnought I - IV
Capital Hybrid Turret I - IV
Torpedoes IV - V
Citadel Torpedoes I - IV
Advanced Weapon Upgrades V
Tactical Weapon Reconfiguration I - IV
Skill cost of about 155 million which is not a lot (and I'm not even certain I need the Captial Hybrids skill... do Phoenix pilots put a hybrid weapon on that turret hardpoint ever?) and it will take about 80 days (~73 if no Cap Hybrid) of which over 32 days is for the Siege mode. That is to say, I could be in the Phoenix firing Citadel torpedoes in just over 40 days. Compared to the year of training for the Chimera, that's noise.
So I'll finish the Command ship training (~24 days now) and then get on the dreadnought bandwagon.
