So i read on elitist this:
"Lining them up (Synapse springs) with Pillar boosts their effect by 20%. Delaying them (assuming 553 ilvl trinket, upgraded twice) gives you Springs every 84.5 seconds, a 29% drop in utility. 1.2*0.71 = 0.85. Not worth it.
It makes the upgraded heroic warforged trinket quite nice, though, with its even 50% increase. All CDs are reduced by an even 1/3, making it much easier to line them up (at least sometimes) with other things that aren't reduced."
But should i still wait to line them up, when the t16 frost 4set comes in play? Aka the icy spike.
