You obviously didn't play as a Warlock, let alone have two in your party. Hex is a CLUNKY TIME-WASTER as currently implemented. It is a spell you cast/re-apply nearly every turn as a bonus-action. The secondary curse effect has little to no in-game effect, yet we have to got through a menu to manually select an attribute to curse. These are the things that begs for STREAMLINING homebrew!
Simply make the secondary curse effect curse ALL attributes AUTOMATICALLY (Warlocks nerfed relative to other "full casters" by near unrestricted access to long rest and could do with a little buff anyway). If for some reason this is seen as overpowered, simply balance disadvantage with a smaller flat penalty to all attributes. Combat has been criticized as too slow-paced, and this *will* save a lot of time and annoyance.
I would prefer they leave Hex as it is in 5e but I can right click on the Hex spell in the UI and it is then set to "Auto-mode" and always automatically uses either the highest ability of my enemy or the stat with what the enemy is fighting, e.g. Dex for archers, Str for two-handed fighters, etc.
