Having the ability to increase your odds of certain factions would make sense. There are some champions that are more aesthetically pleasing to me. In that regard, I agree with the notion of giving players an ability to have at least some control over what they could get.
But, outright being able to buy champions was the stupidest decision Plarium ever made other than the Foli paywall scam. Whales like J who buy their way to the top will of course love it. However, that is a minority. For those of us who prefer skill over buying our way to the top, it was absolute idiocy and greed that caused them to sell him.
If they sold Roshcard, EVERY single whale would buy 2 of him and have immortal teams. The entire game would be destroyed. Or Hegemon, a champion that can take a 58k power team and give it the ability to take on teams of 130k+ in gold IV (yes, there are multiple videos showing Hegemon is God-broken)? Imagine all whales having 1-2 of him. Only the stupid whales (aka spoiled little brats of rich kids) would be dumb enough to believe flat out selling champions is a good idea. Even the smarter whales could see the devastating consequence it would have. The only people they would have left to play were players who *bought* the same exact champions as them. The game would become mind-numbingly repetitive, same EXACT god-broken teams in arena, etc.
The beginning of buying champions outright is the beginning of the death of the game. Hopefully the feedback Plarium received brought them to their senses. Again, having the ability to increase our odds of certain factions, or outright "block" certain factions we DON'T want would make sense. In that regard, I agree. I have ZERO interest in playing with overweight midgets (aka Dwarves). In all other regards, I vehemently oppose the notion of buying what we want. Completely defies the point of this game, which is about RNG, working with what you have gotten so far, etc.
Mark my words - if Plarium continues that trend and moves on to selling legendaries, I GUARANTEE the game will die within 6 months.
