@EdwardDLuffy Do you follow the gaming merchant on youtube? He posted a really good video on the topic..
So here is what I have gathered from the gaming merchant and the videos that have been released.
One of his abilities is likely going to be some type of launcher for Nades and Arc Stars. It appears he has something that can launch them. So perhaps he will get extend range when throwing ordnance? How much more range is the question.. Nades are arc stars are done on timers, so I would imagine their range will still be limited by that. I could see this as a passive or a tactical it depends how it's implemented.
His ult looks like a napalm bomb of some sort. I think this is going to be fun and extremely useful for flushing people out of areas they have camped. Depending on how strong this is it could make.
That's all I've been able to piece together based off what I have seen so far. But in general he does seem like he's going to be an ordnance/weapons legend. I imagine he's going to be an average sized legend.
