Champion Pack

I know Riot wants money and everything, and I get that, but why cant we have a champion pack that gives us all present and future champions like SMITE or Paladins and things like that. I personally think its nice and aside from that, they release a lot of skins that you can only get with money so they'd still make money off of that aspect of the game, I just know that if they had a reasonably priced pack like that, I would definitely buy it because I hate playing league just for the grind to get a new champion and I don't want to throw $10 on the game just to buy a newly released character that is probably not going to keep me interested in the game long enough for it to be worth my $10. I don't know if I'm alone here or what and I know it most likely wont happen because its Riot but I would very much enjoy the game a lot more if I had access to champions when they were released after paying the price for the champion pack and it would probably get me back into playing league again. Until then, I'll just keep hopping on the game once every week or two just to slowly gain enough IP to buy a new champion to keep me interested in the game because I want to get back into it and play it again but its just that the grind for a new champion isn't worth it to me.

EDIT: I just posted this to vent my thoughts because it's been on my mind for a while and bothers me that it isnt a pack in the game that you can buy because It'd make the game so much more appealing to me
