User blog comment:Cybersteel8/New Atma's Impaler suggestion/@comment-2112140-20140721071742

Atma's has multiple problems (such as unneeded crit chance and encouraging HP stacking over resistances) which is why it isn't as good as it used to be. We've got items like BorK or DFG who help us deal with high HP targets that were annoying to deal with in S2. A change I could suggest is to make it an on-hit item dealing x damage + (x% of your HP) and also making it give attack speed like you've offered. This would open up the item to on-hit builds especially those that include Frozen Mallet. Also League lacks items with attack speed and armor so that'd be a new addition (armor and crit has little synergy when you need HP to get the AD) I like your second suggestion better as it includes cooldown reduction and cooldown reduction is a very great stat for tankier champions and it would help champions like Garen or Renekton more since they are kind of AD tanky casters with reasonable AA damage.
