This thread only proves that sets that require 5pc at all times need a review and remove how they function.
For example, Daedtric Trickery starts it's cooldown first then the proc second and you don't control what procs, while wizard reposte from the same damn DLC gives minor maim 15% dmg reduction to everyone that crits you on one bar.
trickery should be giving buffs first, then letting you bar swap so you don't need the set on both bars. In fact, there was a video showing you can't even have that set with 4 body and 1 weapon on each bar otherwise the cooldown would reset each time you bar swapped lol.
ZoS should make 1-bar the focus for PVP meta moving forward, or find ways to incentivize having 5pc sets constantly on.
some sets also will be only for backbarring with summerset.
for example 5 wizards, 5 transmutation, 2 skoria. both last set boni from the 5 piece set only on a sword and sheld backbar. this enables to go master, AS or MSA weapons on frontbar, or 2 items of willpower (or one item in the case of 2h and staves). same counts with others set, where you can squeeze out the last bit of a build.
I really believe willpower staves/agility 2h will go up in price by a lot next patch.
