I understand your viewpoint but would like to shed some light on some things you are missing.
Malzahar is indeed perceived as "not-so-great" in most tiers of play (due to difficulty of play and reliance on farm) but he is actually considered god tier in competitive play (ask any top tier player especially in EU). The reason he only sees "some" competitive play is because he is banned in 99% of those games. The only time I've seen Malzahar been able to be picked is when Reginald and Team Solo Mid manage to get him in the draft against other not-as-high tier NA teams.
We are not remaking Malzahar at all. We are really just aiming to tweak some of his high end extremes (which should only mainly affect high tier play) and make his damage output more consistent between different tiers of play. This mainly has to do with the insane potential damage Null Zone can do combined with Nether Grasp and other coordinated CCs. The amount of damage Malzahar can do is pretty absurd in a skilled and coordinated environment, I can math it out if you like but I'm sure you can come up with the numbers yourselves. It is a normal thing for Malzahar late game to kill enemy champions with Null Zone (W) + Nether Grasp (R) alone. To me that's unacceptable.
Regarding Alistar, he was never considered trash by high tier players. He has always been the ideal tank with extremely strong CC/initiation and a very low reliance on farm. He struggled though in lower tiers of play because he is a pure tank who needs good teamwork to make pay off. The goal of Guinsoo's Alistar remake was to make Alistar more viable in lower tiers of play and in general just more fun to play. Alistar was played a lot in high tier before the remake and that was one of the factors for why he got delayed for so long. We knew Alistar was already extremely strong but just underplayed. We needed to make sure we made him a stronger pick in low tier play but keep him relatively the same for high tier.
Alistar and Malzahar are considered top tier picks in competitive play but "trash" in other tiers due to their reliance on farm and/or teamwork. We are not remaking Malzahar but we do intend to tweak his high end numbers and make him overall more consistent in his damage output.
