Thanks for the clarification.
With respect to difficulty, this is not going to change. I don't think it's constructive for me to get into how many other player groups have dominated Elite Mecharydon, and there's no need to rehash the methods that are required to defeat him effectively. Sorry that this isn't something that you enjoy right now but I have a feeling that as time goes you'll come to completely massacre Mecharydon! :-)
As we're not going to adjust the encounter with changes requested in the OP, I'm closing this thread.
Best wishes!
