What is the actual counterplay against some of these items?
I really hate that as soon as my lane opponent buys one of these two items:
or 
basically means you've lost lane.
the gunblades active is SO overtuned.
UNIQUE – LIGHTNING BOLT: Instantly deals 175 - 250 (based on level) (+ 30% AP) magic damage and Slow icon slows the target champion's movement speed by 40% for 2 seconds (700 range) (40 second cooldown, shared with other Hextech items).
but wait, they also get to heal for 15% of ALL damage done! Magic, Attack and TRUE damage.
and then there's hexdrinkers passive: UNIQUE – LIFELINE: Upon taking magic damage that would reduce maximum health below 30%, grants a shield that absorbs 110 - 280 (based on level) magic damage for 5 seconds. (90 second cooldown)
What is the actual counterplay to these two items.
and don't you dare say 
because its a hunk of junk in comparison to hexdrinker.
for the gw or build the gw applier for your class (but not tanks since it hasn't hit live yet)
