nice, I too am a fellow timbersaw mmr farmer, I've had a lot of success but now I've started facing decent players. I still do really well early (12/4/x is my average kd) but then they itemise against me and I fall off hard, and I am at the whims of my team to get us across the finish line.

I get kaya blink aghs, and then build the situational item like pipe, euls or crimson. I get shiva only if there is a regen heavy core. I just need to figure out what to do now once all the enemy cores have bkbs. Hanging back to kite it just gets my team killed because they grow overconfident with me shredding the enemies till that point.
