Besides giving a Defensive buff and allowing diving/repositioning, have you ever tried dashing with the Drakon's shield/bashing with the Mask's invisibility?
I mean, you got flames around you, dash into enemies and literally damage them all in your path. Bashing might work too, but it's a bit more dangerous.
For the invisibility, dashing DOES cancel it, so it is practically useless, but have you ever tried repositioning yourself into a lot of enemies just to bash them all away, even stunning them and helping your team Sudaruska/Blitz/whatever them?
Besides, let's assume you just used your ER becaue you were surrounded by a ton of creeps, just use the Drakon's shield and bash to get out safely or try to shieldbump them and then go invis with Mask.
Also, remember that rocket puppy room at vanaduke? Don't have a AP with you or something to deal significant damage? Just go invisible and go past it.
Just found out, bashing with invisibility does NOT cancel it.
Neither does shield bumping. You can troll "friends" by shieldbumping lumbers into them. :)
