With franchising I feel that teams will continue to actually try, some people feel that certain players/teams won't "try" because they're 100% locked and it just doesn't work like that honestly in sports, each game, each split, each year you need to produce or you're gone. With franchising I think teams will actually pull out comps that are different from the quote on quote "meta" and we could see a wide variety of champions, plays, and overall diversity in the league because the players know the team is safe from relegation, and for the most part the players are safe to some degree( again, if they don't produce on a day - by - day consistency they're gone) but such "cheese" comps can honestly help NA.
Look at NA at RR - sure, EU didn't really stand much of a chance but NA was facing another region with a different team comp and at Worlds those different team comps is what gets teams out of groups( not just NA's thought of copy paste Korea- TSM) but similar to Albus Nox Luna/Flash Wolves/Origen those different comps that surprises teams and make other teams think outside of the box instead of just playing within the box for a year, going to Worlds with 1 scheme that was practiced for a year and honestly, getting pawned!
Look at C9 for example - They came into the scene with team comps that in NA we didn't see much or even at all and they took NA to another level, Immortals while they were a little too early on such comps the showed they were ahead of their time, so I do think if players/teams know that they are safe and not have that at times over-powering thought of relegation we could see a more powerful region as a whole.
So Overall, do I like Franchising as a fan RIGHT NOW on PAPER - YES, do I know "ALL" of the potential and possible consequences that could follow such decision - NO, but we have to give a benefit of doubt to a company that isn't us but instead a company that makes big boy decisions and done so in the past also.
