Hello, I will try to keep this short =)
My suggestion is basically make us able to use something other than the elite skill in that skill spot, it may create balance issues, but I am sure it will make things interesting and we would see many builds.
I am suggesting this so we can see more builds and more fun builds, we will see more builds everywhere I guess, wvw, spvp and pve.
If it didn’t work, it is not something that you can’t revert, you can always test it, if it didn’t work just pull it out =)
GO ANET make a poll for it so we can vote! =)
