Wow, lots of calls for a VI ban . . .
Honestly, I think VI is necessary for an interesting meta. It gives you options within popular builds, which in turn allows you to beat out other popular builds. The meta last year was all RAC/Fel and Fat Han; but at least RAC had the option of Predator or VI. Heck, VI was just about the only reason Brobots were properly viable pre-Crackshot (thanks to the meta at the time). If there's no uncertainty as to the PS of certain pilots, there's a lot less variance available. It helps to make so many builds viable -- including Brobots, Phantoms, Poe, Fett, and more (at various points in time).
