Was the elise change (Reduced sustain for extra AS on her escape) worth for you ?
She doesn't get as much sustain as before (spiderling doesn't heal her anymore) So her early gank suffer from it (Even if you do the monster attack reset trick with her spiderlings). And an AS buff on her escape doesn't help her. If you use rappel as a gap closer it's risky, and honnestly, it's not worth the very few extra damage.
Also, remember that a single Auto with BOTRK will do more damage than an elise Q (Human).
Playing her as a botrk-fulltank could be good though. You get 240% AS, but it it's dangerous to use rappel offensively.
