As long as i get to be the frog
I ran a campaign starting at zero up to low teens where I used int for initiative & it went ok. We did 3d6 in order but reroll the whole array if you don't get 2 stats over 15. It didn't really help the evoker wizard much at all but was at least somewhat interesting in that the dexrogue didn't almost always go firstish. Since it's relevant int across the group was 15 on a druid, 13 scorlock , 11 rogue, 18 wiz, 15pally. In nearly any other game using normall stat generation noboody would have played the wizard & everyone would have an 8 int making it not very interesting. As you note, despite @FrogReaver's attempts to claim otherwise wizards just aren't that impressive in 5e compared to warlock & scorlock.
*Got it from one of coleville's videos... While it made for some interesting & unusual class choices forcing players outside their norms I'll probably not try it again in stock 5e as it made for some really powerful scorlocks in the group & the only characters who remained interesting to the end had a 3 in dex(fighter) or a 6 con(paladin).
When someone asks you repeatedly to leave them alone you are supposed to leave them alone. This is the fourth time now.
