Seriously, more than half of the champion pool is completely unplayable because champions like 
are so good at doing everything that unless you're going to play every game countering them, then you're basically just accepting that you're going to lose 3/4 of your games.

First, blind pick is hardly serious, usually offmeta/trolls, and really only for casual practice and goofing off. Second, no? Just about anything is viable in blinds, far more than draft.
deadlychuck1 votesI'm never said blind didn't allow for more options, but as far as viability is concerned. You can't go into a game with the same information you would in draft, and that means you will often, in effect, lose from the load screen. Riot keeps balancing for the ranked gameplay, which is why it's acceptable to have these extremely powerful general purpose champions who really only consistently lose to very specialized champions.
