Played a Yasuo vs Katarina lane
I did well at first. Then after my first back, I had a zeal extra sword, and boots. She had a wisp. Then her combo, without her ult, plus her ignite 100-0 me. After that she pushed the wave, stayed, I got back to lane, she 100-0 me this time, with her ult, under tower (she baited my windwall, my fault). Then she had enough for a luden's and I had Shiv and tier 2 boots (greaves). That was gg. Her q did 1/2 my hp through my shield because of that stupid luden's proc, without being popped. I rushed a hexdrinker after that, but I kept dying anyways because her q e w did 100% of my health bar, or 3/4 of my full tank gragas jungle's hp bar so long as she had her ludens proc up. My conclusion: time to main Katarina rushing luden's echo
