She can be pretty tough to deal with but I do think at the lower levels a lot of players just feed her due to their bad positioning/game awareness. I play a lot of Vindicta myself and most of my kills, particularly earlier in the game, come from picking off players who over-extend or aren't paying attention to the mini-map. I had a match the other day where the enemy Vindicta ended up with 28 kills and an insane souls lead because 3 players on my team were repeatedly going deep on their lanes despite a souls deficit. I don't think I died to her once and the rest of their team was beatable, but these guys on my team fed so hard that the Vindicta became a nightmare to deal with late in the game.
