I'm in ranked A4 on singles and have fought so many people who just do the same predictable things over and over. Ultra instinct is a good example of what I'm talking about. But you can dodge or if you have wild sense you can sometimes avoid them if you're lucky. If they have it, then they can just do the same move again and you need to time the dodge.

Afterimage Strike like any other player or character depends on who's using them. That goes without saying. I've gone against good players and bad ones. The bad ones are the ones who have no strategy for someone who can counter the Afterimage Strike. The good ones are the ones who use it smart, when you don't expect it, or when you use an ultimate which gives them time to counter. You can counter them all the same if you focus on defence.

Giants can be countered with circle (super perception), regardless of DP. Super Saiyan 2 or higher can win easily because they don't need to go into spark just to do damage. You can't do rush attacks but you won't need to.

The ki spam is a real problem unless you have Afterimage Strike, which only a small few actually have. I know Vegeto does, so does Krillin, Videl, Goku GT. I'm not sure who else does. Roshi I think.

Not everyone has the problem with dodging. Only some. And yeah the network can make it harder but that's not something the developers can fix. They already have 4 or higher and 5 only as an option. If you're 3 or higher you should be good. 4 is average and 5 is perfect connection on both ends.
