I honestly think shield stacking needs to go. Once a target gets shielded they should not benefit from additional shields for a short duration. Or make them replace rather than stack. It gets ridiculous having a Cait have nearly 4k in health from shield sources. And Janna shields needs a hell of a Nerf.
I agree. Bursting the damage threat of the other team down, for them to then get 2-4 shields that are as much or more then an off tank is a problem.
Alot of people thing the entire games number one issue is damage creep, but in my opinion it's everything creep. I've only been playing for 2 seasons, but even in that time everything has gotten bigger. Healing shields and damage. It's all gotten bigger.
You can stack AD, crit, life steal, and damage buffs, why shouldn't you be able to stack shields?
