Reverting Ahri immediately after bugfixing Liandry's to not amplify true damage seems odd to me.
Since I assume reverted Ahri will have her special case where Q's true damage can be amplified by charm (otherwise what's even the point of reintroducing charm amp if it doesn't work on half of her main ability), which just strikes me as odd when Riot goes out of their way to make true damage unable to be amplified by anything else.
I don't take any issue with the revert and I know Ahri fans probably appreciate it, I just find the inconsistency regarding true damage amplification... odd?
