Berserking values tested both on everlook and classic era for Fireball (default cast time = 1.5 seconds)
Classic Era cast time ranges from 1.35 to 1.05 seconds, calculated as 1.5 0.9 or 1.5 0.7 respectively.
cast time on Everlook ranges from 1.36 to 1.15 seconds, calculated(and rounded) as 1.5/1.1 and 1.5/1.3 respectively.
Attack speed is also calculated in the same way. Suggesting to adjust Berserking to make it more blizzlike.
