Grapeshot auto target and timer
It's unfortunate that when you cast a spell with storm and it resolves as the timer is ending, it automatically targets yourself. The last game I was playing, it was around turn 5 and my opponent had nothing on the board. If arena didn't target myself with grapeshot I would have won the next turn anyway.
This absolutely has to be fixed, especially in competitive play since I end up losing more to the timer than to actual skill, and it just isn't fun to lose that way.
I suggest that while resolving triggers or spells on the stack, the timer should pause to allow the triggers to resolve, that way we don't have to lose to the timer. I also think it would be a good idea to increase the timer in competitive brawl since it takes a lot of time to combo off. Like come on, it's supposed to be ranked! Why are you making us lose games in ranked.
