Most respected hero to lose to.

If you lose to someone what character do they have to be playing for you to say, "Damn I lost but they were playing X so they just legitimately outplayed me." Like it could be a character you consider underpowered or a character you feel is very hard to pull off. Personally when I am beaten by a good warden or lawbringer I am usually left saying "Damn, good play."

Edit: So from the posts I have seen it looks like these are considered some of the most respected characters to lose to:

Warden Lawbringer Highlander Nuxia Shigoki

Gotta say the Nuxia and Shigoki were two I would of never thought of but the rarity of Nuxia players it makes sense. Thank you everyone for the discussions they have been really insightful.
