Why? He's not dangerous. I wouldn't waste throwing axes on him. Lancers are a lot more dangerous.
All Rohypnol does is pad his score by picking off peasants, late spawners, and then kite some people at end when its like 15 vs 2 and then while flags are going up.
Let's be honest for a minute.
Roh is bar none the best HX on NA. Maybe EU, I don't think they have many over there.
Roh is at least top 3 lancer cav NA. He's also decent in melee but that's definitely where he is the weakest.
I think a lot of people aren't willing to admit that he's a legitimate threat because they are too busy being angry about him. But to say "he isn't dangerous" as a HX is simply wrong.
Because of his high maneuver via riding and +3 arabian as a shielder you won't be able to touch him - you will either get hit when you try to swing, or you'll take a bump shot when trying to turtle. As a non-shielded melee you really just need to hide somewhere.
The ONLY way to effectively take him down is via range. The reason he ends up living through a lot of rounds is because people don't target him, or they target others. Meanwhile the round will dwindle down to a handful of players, and hey look there isn't enough ranged left alive to kill Roh's horse, so he has a good chance of winning the round.
Don't get me wrong I don't think HX needs to be nerfed, nor is Roh unbeatable at the end of the round, but when you say he's "not dangerous" I think that's more what you wish was true instead of what actually is true.
