Soulstealer on Janna is an anticlimatic abuse case that should be dealt with
Mejai's Soulstealer is supposed to be high-risk, high-reward snowball item.
It should not be a way in which you get good stats for cheap price because you are playing a champion that needs your conscious effort to ever die( proof )
Janna building Mejais is the most anticlimatic stuff in the game.
