An issue about Adaptive Helm
"Unique passive: taking damage from a spell or effect reduces all subsequent magic damage from that same spell or effect by 15% for 4 seconds" While this is a good counter to DPS spell like Singed or Swain or Malz (etc...), it may be annoying for spell with short CD. If you have a 3 seconds CD spell, you'll have to wait 1 seconds (to reach the 4 seconds) in order to maximize you damage. Unless you can clearly visualize that the "shield" of an opponent is up, it is going to be annoying to focus and count 4 seconds each time you use an ability...
