So, here's the last roster you pasted earlier. If there are other significant updates, you should definitely post a new one. Given the below roster, Kalva definitely would help, yes. You have a ton of excellent support champs already - I don't think you need to bring Vogoth to 60, except if you are planning on building out a CB team. What you're lacking is waveclearing for dungeons, and Kalva will make that much faster.
