In order to let EVERY CLASS have more game option and also make that Elite slot power deserving its name here I suggest the changes that would benefit EVERYONE.
Just let that Elite power slot have this set up :
We would be able to equip ANY power in that slot either from healing lines or utility lines. And any power equipped in the elite slot would benefit a 20% bonus time reduction on Cooldown and also 20% bonus in every aspects that this power is giving.
Please give your feeling about this suggestion that in my opinion would benefit EVERYONE and make Elite power slot worth its name.
