Damage is not out of control....sustain is
Katarina literally healing 40% of her HP per second. Yasuo soloing entire teams. Riven healing like we mispelled Mundo. Seriously, this is out of hand.
There are like 5 sources of free healing (and not a small amount of healing mind you) in the runes alone. I have seen people completely ignore all lifeleech items and literally facetank 3 people because "mechanics."
self sustain needs to be gutted from the rune pages and buffed on items. This way, people atleast have to spend gold to ROFL HEALZ
