Here it is:
Maybe unpopular opinion but I disagree.
RO already is an easy game. When you make such changes, people can just braindead spam buttons with no risk at all when current behavior requires you to have decent timing and targetting skills. I think it's healthy that this debuff has this downside/risk part on it. Good use of the skill will give a reward, bad use = negative outcome but also easily removed. This game is getting so easy I could train my dog to play it. @swap, enemy only gloomy etc are already stupid enough
It's similar to asking for manhole/escape trap to only affect enemies. I can also say there is no benefit in doing those to a teammate but that helps give balance to the skill. It limits usage and makes the player learn/think of proper situation, timing and place to use them. It's not about "wanting" to debuff an ally. Of course you don't want that but it doesnt mean target mechanics should be changed. Otherwise why not ask for cluster bomb to affect enemy only? Why would you ever wanna kill a teammate?
When you say "before i could echo song they get killed by something" (which should be a very quick echo song since you're the one who casted harmo) you know it's not as simple as "The opposing team can just ask for echo song from their minstrel anyway."
