Is this houserule preventing effects from dropping creatures to below 1 HP if they make their save exploitable or broken?

This is going to be a poor idea As other answers point out, this is going to make save-targetting spells significantly weaker, but there's also another problem you might not have thought about. Being ...

Can you roll for HP at levelup in Adventurers League?

I found it, page 5 of version 7.0 of the AL players guide. When you gain a level, use the fixed hit point value in your class entry. You can’t roll your hit points. Missed that but easily fixed.
