Demon assassin should have base speed 6.3!! (it really looks slow to me here, probably his max is 6.0) It is totally notorious that fast-agile-deathly-demon-'alien'-reptile-assassin have 6.0 speed while that Lord Erebus (general with most versatile abilities) have 6.3!!
Really! I know he has passives which would give him +speed(15%, even more on ulti lvl(15) probably), and +dodge,(& +crit),ect,ect. ,BUT that requires lot of skill points to invest. If someone wants to make build with all actives abilities, +dodge for ex., & without any points in speed, he'll have slow 'reptile dg'. Thats bad!
I would like he has base 6.3, but that his passives give less. Actually that the passives are more mutually combined one with each other. That is that 1 passive gives both little dodge+speed, or dodge+crit, or speed+crit . make it mixed, make it original. Ppl have already told that his passives give less than other dgs passives; for ex Sedna's inner grace maxed is +15% plus + 20 hp!, TB's fire aura is +15% AURA speed + attack aura bonus! Really, that is not good balance in my eyes. DA must spend 3 points to get less power than TB or Sedna (in example) for that 3 points. And still he will not be faster than them!!! (with equally spend point & ofc without any speed items (on both sides!))
Cmon!! You can do it better!
P.S.
he really looks like he's running in a spot (gliding)
