Vega Lockdown issues

I’m trying to start maining vega and have been doing pretty well, but I always run into a similar issue, basically I can’t deal with close jump-ins and lock down characters like rufus or cammy, that just keep dive kicking over and over. It seems like vega’s normals and specials are too slow on startup to stop moves like this, but then again im relatively new to the character so was wondering what strategies there are with vega to avoid being totally locked down and unable to do stuff.

Should ask in you character specific section. Im sure you will get more help there
