Anyone else feel that Vikings drew the short straw on the zone feats. Samurais Arrow Storm Feat does massive damage, and effectas a much larger zone as it moves. The knights Catapault feat is a guarenteed kill basically, and doesnt hurt team as much. Meanwhile, the Vikings zone feat is not a guarenteed kill, and does massive damage to you and your team if you get caught up. I guess the upside is that the fire lingers, but that is just a s dangerous for your team as it is for the other team.
Arrow storm does high damage if it actually hits, but each volley is so narrow, anyone that's paying attention will most likely dodge it immediately, I stopped using it long ago. Fire flask at least provides long area denial and can be used anywhere. Using it inside cramped rooms and stairways is an almost guaranteed kill.
I'm not sure about the others but I think the catapult could use a little bit of a speed nerf. I can't tell you how many times I saw it was coming and tried to roll out of the blast radius only to have in crush me mid animation. It's seems like if you are near the middle when it's called in there is no escaping it.
