I guess with moba is that it makes certain classes, tricks and play styles less viable, and if you're playing casually then gamefeel is mlre important than toughing it out for grinding rank. My reference point is Pokemon Unite.

Speedsters (fragile jungle, melee combo, high skill floor and ceiling class) became frustrating to play at 100fps and above, because if you miss a combo, the game doesn't register a hit in time, or get stunned out of a move and can't full heal (remove status conditions including stun) then you're done for.

Between 100 and 150, ranged auto-attackers are basically fine so long as they pre-run from threats early, trick-shot attackers have to compensate for lag/doubly lead their target.

150 and above, my experience was that the only playable classes were supporters (AOE healers/buffs) and defenders (CC) which just have to worry about position between allies and enemies.

150 and above yes it's playable but it feels sluggish and isn't enjoyable. On Pokemon Unite, the Oceania playerbase isn't large enough so I was often dropped into SE Asia servers and my winrate would tank, so I stopped playing, and I wasn't willing to play exclusively defenders/supports to prop up my WR on SEA servers

I knkw for gamers here this may be more or less kf an issue depending on their preferences or what they play. My friends who play moba and fps complain at much lower ping than i do :/
