Which hero are you playing, and why?

Champions of Stone sorts its heroes into six roles: Tank, Bruiser, Mage, Marksman, Healer and Support. Which ones people actually gravitate to is another matter.

Post your pick, what you build on them, and whether they feel strong or weak against the bots. If a hero feels useless, that's worth a post too, because it's probably a balance problem.

Who do you keep locking in?
