[1.2.355] More balancing

The delay changes to Arrow Rain/Eruption make them super crappy. I almost never ran into mobs of more than 6, except I could lure because it was fast enough. Now, it's so slow you can actually get killed using it to lure because of the amount of damage it would draw. Maps where monsters exist in mobs greater than 6 require that Arrow Rain/Eruption be at standard speed so it can actually KB monsters. Since it's this slow, you're basically just drawing aggro so you can get hit instead of efficiently killing monsters.

Ice Strike getting a speed decrease makes no sense at all since it was already slow to begin with.
Barrage was already a shitty skill, it didn't need to become worse.
Dragon Strike nerf is almost as bad as Arrow Rain/Eruption. Just denies more mobility for Buccaneers. Unless it gives them more invincibility frames, which I would guess it does the opposite, it's a needless change.
