I'd also note that what's in your head still isn't reality. I already pointed it out when you complained about Smoke Bomb n pages back, but would you mind explaining how a hero that is fine can have an ability that is OP? You don't get those abilities on any other heroes, it makes no sense to say something like "Riki is fine but Smoke Bomb is OP." Either the hero is OP, maybe because said skill is OP, or they're both fine. Smoke Bomb might be OP on Krobelus, Storm Bolt might be OP on Rubick (as a base skill, considering he is one of those heroes with a separate nuke and separate CC), but unfortunately only Riki and Sven have access to them. With the exception of Spell Steal, of course.
Besides, how do you make Double Edge extremely great farming ability if you first have to invest in a ton of HP regen to keep using it? Does that differ much from how some other heroes could invest in mana regen or BF to farm? And how is "someone can buy a veil to boost it" not something that applies to any hero with nukes?
And this would be the third time you launch into an explanation about how super Double Edge is? What, did you think someone didn't get your opinion yet?
