I can't really say I'm deterred from playing OU, it's still my main tier with Ubers close behind. I'd say the current metagame is actually pretty balanced, (with the exception of hail) I don't think any one weather condition outclasses the others. But yeah, weather wars in general can be horribly exhausting. Unfortunately, losing your weather inducer can lose you the game. So it's incredibly tedious when you think about how losing a single Pokemon can reflect the outcome of a match. That's my only real gripe with OU.
