I haven't really looked at the game since S16 of GLB1. Back then, it mattered when you made your player for boosting.
If I am thinking about coming back (with some friends) does it matter if we make a player before this current season ends? Will we be at any kind of development disadvantage?No disadvantage - but if you select to build an experienced player, you will then be entering sophomore season instead of rookie season.
There's no advantage to boosting later like there was in GLB1. Most competitive teams boost at the start of a season.
Rookie (first) season is very competitive unlike GLB1 where everyone just tries to set up for future success. Obviously it is up to you - I would strongly suggest taking a season doing player building before diving all-in on building a full team with your friends.
