With more champs being added, riot should give more gold. Luck is a factor to getting the right champs you want, and the higher the champion pool the more you gamble your gold.
Why would I be forced and punished to build other team comps that I don't run? TFT is supposed to be all about how "I" make my decision and build paths. Adding a Meta to such a thing would obviously make this gamemode trash. I like creativity and not getting forced to build the same thing as everyone else.
They clearly stated they're not quite happy yet how easy it is to force a comp which is exactly why they'll add new stuff until they have a full "set". So no, they wont change that. It was the intended effect.
Don't expect to many new Champs after Hex. Maybe one or two to fill up some existing synergies. Wild and Noble comes to my mind.
I know there are a lot of people out there who feel the same way. They have too much champs in TFT right now that the econ is dogshit. Can't get the right rolls or just have to spend too much gold since all i ever see is camille on my screen or something else that I don't need. At the end I could spend a good 100 gold and still not get my roll that I need.
