So far on very quick initial thoughts.. My only gripe is with the R.
They seem to have basically just moved null zones % dot to R, which for me the R damage was my one reliable way to counter 'burst assassins' that pop in, nuke you, and pop back out (zed, lb, etc)
As moobeat said on pbe forum, you wont be able to burst squishies with ult anymore.
I wonder what kind of total % damage will be attached to it.
So now R will be less effective as being a counter for those burst assassins, more just delay your impending death until the suppress ends.
