To answer your question look at the "all sources" part of the dmg amplification. Most tanky champions build thornmail or sunfire. Now that damage gets multiplied by 2%. Most tanky champions have DoT values on an ability. Now that damage gets multiplied by 2%. They are force jacking the skill; just in damage from a bunch of abilities and items rahter than from a single stat perspective. Another reason why pros might want to take this is that 1% of dmg is not equal to 1% of dmg received. Because of the way armor and magic resist work the more you have the less that 1% dmg your taking.
