I made a Lightning Crossbow Deadeye and I'm deleting monsters. Bosses I can kill pretty fast too.

Looking at the passive tree, the only thing left for me are % increases to my damage (just different flavors of it). My best ability is Galvanic Shot and none of the level 3 support gems actually help my build (inflicting Shock for a massive damage boost).

In other words, I've already experienced the peak of this character build. At best I might kill things slightly faster (since it takes me 1 or less seconds to kill a screen of mobs) or I'll just kill things slower as monsters get harder. There are no support gems or passive tree nodes that will make any change to the way I play my character.

Is this normal for a PoE build? With the way people spoke about PoE before PoE2, I was expecting to run into some wacky modifiers that would change my playstyle or build but I've been playing the exact same way since about level 30.
