Galio is the weakest antimage concept ever
other tanks fulfill the theme better and its not even intentional. the only thing Galio has going they didn't was that he has the poke to lane against mages directly.
Maokai passive greatly increases in value against casters, and his ultimate completely overrides one of most mages biggest strength; zone control. Tahm new E works much better against being poked and harassed than it works against all ins, again greatly benefiting his effectiveness against AP threats, and his R flanking potential helps him a lot more at ambushing squishy targets than it would a juggernaut or an assassin who can easily escape. Both of these champions (Mundo, too but he's not a tank) also have better access to actually buying MR items because Spirit Visage - one if the core MR pickups - works well for them and sustain is a big counter to mage burst when combined with durability.
Galio gets a one-time magic shield and some magic reduction, otherwise the rest of his kit is mediocre at tanking/locking down mages and is much better at contending divers -- putting him at direct odds with Poppy because he's stepping on her niche.
Compound that with the fact that he's completely a grief pick right now (less than 1% pickrate and horrible performance) and its looking pretty miserable. At what point can we finally say this rework did more harm than good?
