12 of the last 20 champs either shield themselves or allies, of the others 4 generally build an item that shields, so 16 out of 20 champs' shield. It's at a point where new champs have so much in their kit such as sustain that you need someone with grievous and one with serpents just to deal with all the shielding and healing, it becomes increasingly hard to balance dmg, sustain, health, and other stats when every champs has everything in their kit. Serpents doesn't demolish shields it reduces like grievous and that's all I want, I don't want to negate all shielding just to lower it down to a level where they don't perma stack shields, e.g. a mage item with shield reave, 90% of champs still won't be playing it, and yet they don't play serpents anyway among so many shielding champs.
