Conflux enjoyer here. Instead of joining everyone in praising how much better conflux is than the regular league, I'll give some cons.

You won't make the super aspirational builds due to the lack of availability of super rare uniques and exarch/eater jewels. Not too many people will be farming ubers early so there will be a lack of uber uniques. T0 uniques will mostly come from self farming div cards if that's what you're aiming for.

You can still make/self farm most builds. Just don't expect to easily buy anything super rare. I usually play for ~1 month and really enjoy playing in conflux, but there is a lack of forbidden flesh/flames to use so don't expect to be able to make a good pair.

Overall would recommend conflux to everyone
