in current league most mages have to build deathcap because of the absurd AP value it grants alongside void staff for the pen if there’s at least one tank, and assassins and burst damage dealers forcing you to buy hourglass, most mages had these three solid items every match, which is pretty lame. I would love to see deathcap nerfed or removed, and void staff changed so its only viable against tanks. on the other hand, shadowflame is turning into another must buy. with the effect:

• Passive - Cinderbloom: Magic damage and true damage critically strikes enemies below 35% health, dealing 20% increased damage (reduced to 30% increased damage for damage over time and pet effects).

it kinda reminds me of those WoW talents which increased your damage against bosses in their last 35%. and it not only helps to bring tanks down, but also squishies (looking at you, stormsurge). so I would like to see it work only on low resist / max health targets, or high resist / max health ones.
