Again I ask: are these rolls being done in front of others, on the table?
I'm sure they won't have been...
We're playing a 1E campaign, 4 players, each has a pool of 4 characters to choose from. 5 characters have died permanently thus far - I no longer have the stats for those. 3 have died and been brought back by some means. 3 characters have been level drained by undead at some point, 1 character has been level drained twice. All the characters were rolled at the table using the normal 4d6 method and started with max hp at 1st level.
We have:
16 characters now at level 3 or above, the highest has reached level 8
Of those 16:
5/14 single-classed characters with a +10% xp bonus, and one of the multiclassed characters has a 10% bonus in one of their classes.
2 multiclassed characters
2 Fighters with 18/% strength, the highest being 18/75%, a human female who moved above normal maximum by magical means.
One of the fighters with 18/% strength has 2 stats below 6, and no other bonuses beyond the strength.
5 Fighters or Fighter subclasses with a strength of 15 or less, and therefore no hit/damage bonuses.
2 characters with 3 or more stats of 15+, 1 is a Monk, the other is a Cavalier. The Monk has 1 18, and 3 17s and does not outclass the rest of the party
3 characters with no stats higher than a 14. (one has 13,12,11,9,9,8)
8/16 are human
None have maximum hit-points for their level! One managed maximum at 2nd and 3rd level, but that soon evened itself out (he rolled a 1 at 4th level).
The main party of 8 have a spread of 3 levels between highest and lowest, it does not cause a problem. 8 of the characters are 'backups' playing a side campaign arc, these 8 are all now level 3-4.
We have a wide variety of characters with different abilities, differing spell selections, hugely varying stats and hit points.
The game is still FUN.
