[1.2.276] More rebalancing

I like the MP reduction to ultimates, but that's really not what needs to be changed. AMs with an ele weapon now do more damage to mobs weak to holy than bishops do with ultimates. But we don't need more damage with ultimates, we need more damage with bossing skills. This patch increased the amount of damage done by an I/L AM with an ele weapon from 315 base dmg to 337.5. That's about a 7% increase in total damage, which is maybe a few thousand more DPS. AMs need much bigger changes to their skills than this. Bandits get an awesome change to a previously terrible skill, a boomerang step cooldown reduction, and a slightly better assassinate; Paladins get a dual charge, which greatly increases their damage; Corsairs have no minimum range, a more durable ship, and more damage when their ship is broken. AMs deserve more than 7% more bossing damage.
