I wish for a patch which gives us more variety in viable laning setups. There was a time where min 0 roaming sup, defensive trilanes, aggressive tri lanes, suicide offlane were a thing. Personally I miss playing a real roaming support the most. Nowadays it feels this playstyle is far too risky by getting not enough gold/XP while also sacking your offlane. The occasional mid rune secure or portal gank feels far more predictable. And from a viewers perspective it felt exciting to see teams outplay their opponents with a surprising aggro tri lane. In general I think more viable lanes gives the game another level of strategic depth which is more exciting to play and more exciting to watch.

PS: also shifting the offlane role more to an intiator/chaos creator than the current carry no.2 would be more fun (personal opinion)
