TFT is falsely named
There's no tactics in it. There's no strategy. You get served table scraps from the champion pool and then get forced to play around it. At literally any moment your entire team comp can become inefficient and you have to sell and re-do everything, and just hope that the items you created (if you were able to get any) are useful on the new team you're forced to draft, until THEY stop being available too.
Did Riot think about this at all? Everybody sharing the same champion pool? Sure, it stops people from building the same units and team comps, but it also means that everybody's going to take the same champions early and then take the same champions to build a new comp later, and it just locks everybody in to a disgusting half-build unless you get REALLY lucky.
The one thing I always hated in League is "ouch, unlucky" in ANYTHING. And now this new gamemode with so much promise is just "Ouch, unlucky" and nothing else.

doesn't annihilate your backline
