Like I said before there is more to balancing than simply just putting a cap on things. You seem to be set on putting a cap on critrate (which is fine, you can desire to have that) but I fear you won't get far. If you want, send a ticket with your suggestion to the GMs and see if they approve of your suggested change.
I'm not saying everything I said before because I think I'm 100% right, I'm saying what I said because I know that making huge changes and capping things is not something the GMs (USA nor KR) are easily going to agree with. Thus putting time and effort in those changes is mostlikely not going to make any difference. The GMs said their most urgent matter is class balancing via skils/buffs so that's what I'm working on, again because that's what they require.
You can have many good ideas and suggestions but if they do not answer the question that's asked, you won't get anywhere.
