I think the Isida is broken because it's not healing other players on my team and i don't think it's dealing any damage.

When will we be expecting this new engine and update?

I'm not sure if I can answer the question in the vlog about the tanks VS mines but if so here is my answer. I think the Titan will survive the mine.

When your in sniping mode with the shaft the a team mate will either push you or if they have fire-bird or freeze cannon will shoot in front of so you miss your shot
