we had something like this way back in beta where FV would hit all targets for half the amount if SotR was active. i dont think anyone hated the idea on it's own as well but they then removed the perk and gave us empowered DS and the new perk that FV has on it now, then they nerfed DS by 30% wpd to compensate....
as for the whole seal debate. seal twisting sucks and always has and this empowered seals shit is not even like it was but it is even worse to boot.
Using a good portion of your GCDs for empty GCDS (aka a gcd which does nothing for you, literally nothing) to then have to use another spell to actually get you a buff ( which you cannot feel at all at least until much later) then having to swap back on another empty gcd is just terrible. i have literally never seen anything like this in the game before. no other spec NOR CLASS has to use ANY of their GCDs and actually waste them on things that do not even help you immediately.
empowered seals is a failure. the only people who like this talent mistake how it plays with what it gives. no one will argue that the haste buff we gain from emp seals is good that is true. but the hoops we have to go through to get that and to keep the other buff up which actually makes up for a majority of the talent's dps is just ridiculous.
As a friend of mine would say,
THE AMOUNT OF STUPIDITY AND INABILITY TO LEARN FROM THE DEV. TEAM IN WORLD OF WARCRAFT IS TWO DAMN HIGH!
(insert random yelling hillbilly or illiterate bastard for more laughs)
and if you did not realize it yet, i do not like empowered seals at all. in fact, i dont think many of our talents are "fine" either and need a good fixing. good example is having unbreakable spirit in a party/raid utility tree..... or having zealotry in the game at all after the constant issues it has always had in this game.
DO NOT GET ME STARTED ON HOLY PRISM EITHER HOLY GOD!
