Suggestions for TFT

I like the idea of the game mode, but I have a few complaints.

-First, if we don't get any kind of control over our pieces during combat, I would like them to auto target lowest health enemies, or switch off of invulnerable ones. -Second, items seem to be either feast or famine and no in between. Maybe more of a drop chance? It would also be nice if they were slightly more geared to what we currently have, champion-wise -Third, the RNG on the champion shop is mind numbing. I've gone either several stages without getting a single champion with synergy with my current load-out, or for example purchase enough Blitzcranks to have two 2-stars, two 1-stars, and not see another one for several stages (In my case, the rest of the game). I think it would be cool if we could purchase that one hero we really need outside of the shop, but for a much higher cost (to dissuade people from ramping what they have without having to use the shop, or even making it impossible. It should really be a once or twice a game thing, for when RNG is seriously failing.) Failing everything else, I would really like to see the champion shop spit out things that have at least one archetype in common with something, ANYTHING, that I have in my load-out. Building, for example, ranger/gunslinger because that's what was available for the first two stages and getting NOT A SINGLE NEW ONE for the rest of the game was very frustrating.

A couple extra seconds to pick the very first champion would be neat as well.
