How to deal with all the Displacement/Knockup in the game

We need to add a Steadfast ability and Size to things that affects Knockups like Tenacity does to stuns/slows/roots

For Size Things have a Size ranging from 1 to 6 Minion (melee, caster) has Size 1 Cannon has size 2 Siege Minions are size 3 Blue/Red are Size 4 Teemo has Size 2 Normal Human champs have Size 3 Cho'Goth starts out as Size 2 and ends at size 4 Zac ranges from size 2 to 4 Barron is Size 6 Elemental Drakes, Rift Herald are Size 5 Elder Drake is size 6

Knockups have a power that will knockup anything less then or equal to its power and interrupt anything more then its power.

examples of knockups Yasuo Tornado has power 3 Sion Knockup is Power 2-4 as he charges it Reksai knockup is power 4 Aatrox knockup is power 2,3,4

Lulu Ult adds +2 to Size

adds +1 to Size

For Steadfast Some champs could have passives or abilities that add to their size for a short time (out side of Zac and Cho) Even some champs could be Size 4 by default like Sej, Sion, Mundo, Malphite, Urgot
