Sometimes I feel the game pushes you towards a build only to deny you key champs later on.
This happens a lot. Game pushes early towards a particular 6-9 champion build, like getting 2-3 2-star synergising champions before everyone has even started to get 5 champions. Then it slowly gives you another one or 2 champions. But then after the third carousel round, you dont get a single unit more. Problem is that you now committed more or less to the build, but are sitting at 5-6 champions and will end up RR 50+ coins to get nothing. You sometimes are not even sharing a build and this happens.
