[GameMode Idea's] Masked Ball, Alternate scaling & Elemental Battle

Hello again, I had another concept for a rotating Game Mode.

Edit: Masked Ball: Since I highly prefer the idea of everyone having a passive that makes you go invisible till you get in combat, sure laning fase is exactly the same since you will be in combat all the time but then later on, ganking or teamfight plays will be a lot of fun IMO, since everyone has invis some champions might be a little better than others but this happens in every game mode. I think this is a minor tweak riot could probably make and would result in some jump scares and fun gameplay. (Champions with invisible would just gain the passive while stealth since they are over the X amount of CD the passive will have. (Except maybe Kha'zix)

Alternate scaling: Invert all scaling effects, everything that scaled with AP now scales with AD (And in some few cases Armor -> MR and viceversa) of course changing the magic dmg to physical damage and viceversa. This small tweak might bring some fun games where you see a zed with 800 ap one shotting or a lux critting you and yet doing dmg with her ult. (Some champs might suffer, but in every temporary game mode tweaks have to be done or some champs just lack power)

Elemental Battle: Who doesn't like some good old elements, it doesn't make sense that Nami heals brand when she splashes water on him doesn't it? Well why not make a game mode where every champion has an element, super effecting or being not very effective against other elements (Maybe every ability has an element assigned to it). For example, playing fizz vs brand, lux vs nocturne, zyra vs nami. For example basics like water beats fire, fire beats grass, grass beats water and then add more types like dark, wind, earth, rock, ghost, light, normal, ... I'm sure this would add some fun counter plays.
