I came back from 1 year break (was previously master rank) - and with new Xin Zhao rework I just had game where I was anivia, xin zhao is standing in my ultimate for 6 whole seconds taking 0 damage, it might sound "not big deal" but in that 6 second my teammates got taken down while xin zhao is standing on full hp? I should've done 5-10K damage in that 6 second but I did 0.
I also noticed Xin Zhao has one of the highest win ratios, no wonder why. Anymore. Untill I read the xin ultimate immunity.
IMO too strong vs. mage champions
