fleet nerf

You may have seen that fleet got nerf on 14.17, it went from 20% speed for 1.25 s to 15% speed for 1 s and 5-120 heal (based on level) to 5-100 heal (based on level), do you think this nerf is enough to remove the rune from zeri and start playing PTA or conqueror or can we keep fleet for the moment ?
