To the people claiming that if rain were to be banned, then it would follow that we would have to ban sun.
1. Currently a lot of non-rain teams run rain checks, a lot of these check's don't enjoy sun (Jellicent, Gastrodon, Celebi) - The demand on these rain checks is liable to decrease and thus options will open for newer team slots that will be able to deal with sun.
2. There are quite literally a plethora of fire types pushing at the edges of UU, waiting for an opportunity in OU. These fire types will rather enjoy a firey metagame and a lot of them check prominent sun threats! For example Houndoom can trap Darmanitan + Victini, Chandelure walls the most viable Sawsbuck/Venusaur sets and Victini has some unique resistances to types that rain teams commonly deploy.
3. Unlike rain, which tends to work in favour of a variety of pokemon (Thunder abusers, Hurricane abusers, water types, bulky steels, bulky grass types, the plethora of rain abilities including some on non water pokemon, etc), sun really only works in favour of chlorophyll sweepers and pokemon with fire attacks. It could be argued that certain pokemon will enjoy the 1/2 to water attacks but in a rain-less metagame we can realistically expect water attacks to almost never be present when non-STAB'd by considering its super-effective coverage, distribution on non water types and the history of past meta's which show water attacks as coverage tend to be rare.
4. The nerf to water types in general in a metagame where we could expect mass sun is not really a problem. Water pokemon tend to be useful for more then just their water stab and the few pokemon that really did need drizzle to remain viable (politoed, vaporeon, etc) will hardly create a "less healthy metagame". If its alright for 2 dark types to be classified OU, it will be alright for water pokemon to lose a few spots in OU (9 current water types in OU for reference).
5. Threats like Darmanitan and Venusaur on sun teams can easily be managed by fire pokemon of your own. Ironically fire attackers will deal with sun teams much better than water attackers deal with rain teams when you consider the bulk of water types on rain teams versus the bulk of the fire pokemon with flash fire on sun (only heatran is truly a bulky fire with flash fire). A case in point: A kingdra against a rain team is often a liability because Ferrothorn/Jirachi/Jellicent/Politoed/Vaporen/Tentacruel can at the very worst check its attacks however there are few pokemon on a sun team that will enjoy switching into Darmanitan without perfect prediction (EVERY OU viable pokemon with flash fire is super-effectively hit by one of its coverage moves).
The "broken" things that stand out to me are dragons being able to more reliably beat steels, however we already know steels aren't the only way for dragon circumvention. Many pokemon such as Landorus-T are capable of baiting outrages and meteors. Venusaur will be much more likely to be beaten in a metagame without rain because of all the pokemon we could expect to rise to OU. That said in a drizzle-less metagame I will be expecting Venusaur to be banned.

Reason: I meant pokemon with fire attacks*** not necessarily STAB only
