It's really fine where it is... higher leveled players don't have problems with it. If they did they'd say something. That's not to say you're a shit player either. I'm just stating the facts. In higher leveled play, using a low defensive hold as means to instantly a crush a high isn't very viable, you're probably better off throwing a a 2p instead for that 5 dmg, and usually that reset. Some get different advantage off that though, like Hitomi, who ends up at +1 instead of a neutral reset. Think about that.
Also remember that Low Throws generally do more damage than their standing counter parts. My example with Hitomi is her i5 grab standing is 38 damage, her i5 low grab is 48 damage, and unbreakable. As for her i7's, standing is 42dmg, crouching is 50 dmg). The reward is greater.
Low hold spam also gives way for you to throw out those more damaging mids anyway.
I mean I've fought low hold spammers and that's when I make them eat 3H+K spam til they get a clue, granted it's safe as hell for Hitomi.
The point I'm making is... It's not a big deal, at all. Really not at all.
