If you had read more carefully what I wrote, I said about lower the CD for potion as a solution. Nevermind.
Yep, this is my initial answer. Short, without argumentation or further informations.
I didn’t say that I hate the CD system too, because I’ve no problem with that. I’ve just said spammable pots were fun in RO, I should have made a precision: IF you don’t abuse (if you use this feature the correct way).
But okay, I understand everyone isn’t fond of these, since everyone don’t see the fun because the others play like dumbass, thinking “lots of pots = I’m invicible, infinite HP”, brainless spamming.
“The others do, so why not me?”, right?
“I don’t know”, it’s a manner of speaking… Because I’m not a game designer, there is a lot of possibilities to bring balance. I think even you could understand that… 
And if people don’t want to use potions, then there’s no problem. No need to debate on the potions’ CD then 
So, for make it simplier: Don’t worry guys, the CD will stay. Maybe lower it on HP/SP potions (at first) will be helpful for solo players.
