I have said many this many times, but the most important way to generate PCs is at game session 1 with the whole group there. We use 4d6-L, but that's from old habit. If everyone shows up with a PC idea and theme, which you should, it take just a few minutes to generate your abilities and get the level 1 sheet worked out. Doing so:
1. Lets you roll for abilities right in front of everyone. If something is out of line the group and DM will decide, something like 6 roles with nothing higher than 12. There wont be any complaints and no one will get upset if you get blessed with a a good set, you did it right in front of them,
2. You start building a group dynamic right there. With life cleric and a Paladin you will see that you can play a Valor Bard. With a rogue in the group your fighter can see that Shield Master will be useful to get those sneak attacks in with advantage. Things like that.
