Real problem with new players leaving
As most have seen in Kabams Q&A video with the big Dork, Kabam is worried about too much gold/resources for new players as a risk in them not playing the early content. They would then get bored and leave. However I have had 4 friends and my son (all playing around 1yr) recently quit all for the same reason, bad pulls. As an example, my sons last 6 5* pulls have been KG, Groot, Red Skull, Miles, Gambit and IP. My friends quit because of bad 6* pulls (DPX, Miles, DPX, Groot). Now I get not all pulls should be Ghost, Doom, Dom, NF, etc, but bad pulls on your rare to get crystals is demoralizing. This is nothing new and most people that play this game have muscles through that struggle, but I have known more people to quit over that than anything else in my 5+ years in the game.
This is not advocating for all champs being similar in level, but there are too many garbage champs that have no place in the game. This is especially true for 6* pool (I have DPX, CW duped).
It just sucked seeing my son quit as that is what kept me in the game after retiring from my Masters alliance.
