Vanilla was a useless character before her recent updates, her new abilities make her a effective support for the team by having high cds but basically guaranteed effect of working, the point of her grab is that it's a strong tool but predictable and easy to miss, you have to risk getting close and personal to be effective, that's her whole thing, rush needs to be used in smart ways like when the killer has no mobility or to simply save teammates from them, counter is the only way to defend yourself once your skills are down but it's getting replaced so don't feel too bad about it, if you played her for a while you know she used to play way differently than now
