Just a question, nothing more:

The damage boost on autoattacks of the ult is split in a 'flat percentage' (30% at level 3) and an AD percentage (20% AD). Since the damage of autoattacks already derives from AD (100% total AD without modifiers), does this mean the 30% of the ult also applies to crits and possibly on-hit-effects (e.g. Wit's End, BotRK)? Does the same hold for the passive? Pressing R then effectively makes critical strikes deal 100% (base) * 2.5 (crit with IE) * 1.45 (.3 from ult and .15 from passive) + 20% (ult) = 382,5% AD damage. That is interesting :) The cooldown seems appropriate.

If the 'flat percentage' bonuses (15% of passive, 30% of ult) does not apply to critical strikes and on-hit effects, they apply to the base damage of an AA only (100% AD), meaning they simply add 15% (passive) and 30% AD (ult) tot her autoattack damage. This in turn means the percentage bonuses of the ult could be added up to read ADDITIONAL DAMAGE: 30% / 40% / 50% AD.

My reasoning and my math could be wrong though :]
