I'm at about 50% Progress so far. I usually have very strong melee characters in games like this. My main one is good, but not quite as strong as I'd hoped. Ranged seems to be where it's at despite their low damage numbers, which is why the only Troops I ever end up using are Rangers. Overall, healers and range seem to be the most used, especially once you start facing the snipers that constantly teleport and Overwatch with every hit and the real melee bosses will have a massive AoE on their swing. Hoping melee becomes more advantageous later on or I might just start over and focus solely on range with a melee as just backup. I also just upgraded his melee weapon, so hopefully that will be the turning point, but and additional 2 damage doesn't seem that impressive on paper at this point.
