I`ve seen a lot of "roll for stats" in Tabletop because it´s fun to roleplay a sickly mage with 8 CON that could die if someone sneezes too hard around him, a 9Wis deaf warlock or an 8 int paladin half-orc in a TT game; but as discussed in another thread, there are little to no advantages to doing that in a videogame because they rarely give you options for characters with low stats, you still can woo the bartender, speak poetry in ancient English or disable complicated lock-puzzles with a 6 int 8 cha character. Dialogues seldom change.
There are games, like Arcanum or the classic fallouts or even PoE2 that added changes for stat-challenged characters in dialogues and quests, but they are the minority. You usually got all the disadvantages in combat and skill checks and zero revenue. Most people just rolled over and over again or min-max because you do not have a real reason to have low stats but plenty of reasons to have high numbers in your main stat, and rolling, again and again, gets old really fast.
This is going to be an MP game, and I found that when you "roll for stats" some players that had abysmal stats and play with lucky characters that rolled three 18s usually felt left behind from the start, even if their characters are very useful in their role even with low stats and they also offer them lots of RP options. I think that could cause issues with some people unnecessarily.
If you want RP a character with low stats (or super high stats), you just use point buy and reduce the stats you want to 8, 6 7, etc... but all the characters will have the same bulk numbers from the start.
From a DM/game developer perspective, I find that point buy or standard array is fairer in multiplayer games, because all the characters are equal from start in their stats at least, and no one felt unjustly treated. That could cause problems with some people in the long run, and in a coop-multiplayer party-based game, you want all the party members to have fun and have a great time.
Sorry for the long answer, but back on topic after seeing what the new cantrips can do I am eager to try a high elf, possibly an arcane trickster. I really want to know what you can do with your mage hand leadermain as a trickster.
