True - on the A319 that is tough. This is of course true of nearly every window seat except a small percentage of exit rows that either have a normal boarding door in front of them, like 9DE/10ABC on the A321, or have a flight attendant seat in front, such as 24 on the East 757.
If you're tall, you want 10A or 10F on the A319 - huge legroom with no seat right in front of you, and underseat storage under 8A/F. You probably don't want any of the other exit seats on the 319.
