Damage through walls is the only thing that saves the game in old locations. Have you forgotten what the map of locations in the game looks like? These are pipes and small halls with a bunch of objects.. In the locations like Kuva and infected ships Los destroys the game.
Dante: The energy is enough for 3-4 uses of “Tragedy”(or another ultimate) , and it can hit just 5-10 mobs maximum. This does not in any way contribute to active gameplay, but on the contrary forces you to sit in one convenient position. People who complain about warframes that destroy entire locations, apparently do not play the Steel Path at all. Dante can't kill high Level mobs by “Tragedy”. He was strong before the nerf, but he wasn't stronger than other warframes, but now he is just useless trash..
