Is Horizon Focus slept on for support Lux?
Plat support main here with a 52% WR on Lux. When I play Lux I go Horizon Focus second unless the game demands I do something else (i.e. I need to rush pen or defense).
It just seems better than Stormsurge on support because the CDR + passive offer so much utility. I've single-handedly won spooky fights for my team with low/no vision in the jungle or around objectives by revealing the entire enemy team. A well placed R if your team is trying to contest an objective they are taking chunks the enemy team and reveals them in the pit even if they are on a control ward. Utility goes up even more if you're facing stealth champions as Horizon Focus reveals them too if they're in range.
Lux support's carry potential is always going to be gated by the fact that you are limited to 4 items + support item. The tradeoff of burst for utility feels great to me in most games and I'm still putting out great damage (and picking up a lot of extra free assists off of Horizon Focus's passive which means more often than not I can afford Deathcap on support).
I don't see a lot of other Lux support players favoring this item and I'm willing to be convinced that my build sucks. Thoughts?
Edit: Luden's first (almost) always. If you blind chuck a spell into drag/baron pit or a jungle camp (and hit the objective/camp with your spell) you'll get the reveal from splash damage even if they juke your spell.
