The Higher POE Item Quantity And Rarity Are On The Map
If you aren't in maps, then you're still playing the babymode content.
I'm not saying there's anything wrong. I'm saying that if you're getting bored with the normal content, it just means you might be ready to start mapping because it's MUCH more challenging. If you want harder content, it is there. Maps are sort of like grifts, but there is a ton more variability and difficulty available. Maps can be modified just like gear can by using transmutes and alch poe orbs to make them even more difficult by adding affixes like damage reflection, permanent player curses and minus max resists. Beyond maps, there is even more difficult content like uber atziri, guardians, shaper, and council kills. Plus, with the breach expansion coming out next week, there will be a whole new layer of content to play through.
Yeah the more painful the affix is, the higher the Path of Exile item quantity and rarity are on the map. Also, some affixes add to the monster pack size. Also, there are some really cool league specific affixes like nemesis which gives all rare monsters a special nemesis affix, bloodlines which gives all magic packs a special bloodlines mod, and beyond which can summon super dangerous beyond monsters and bosses when you kill enemies close together. Mapping is incredibly rewarding.
Voltaxic sparker got nerfed pretty hard, pally. voltaxic rift only converts to chaos damage at 60% now so you aren't immune to ele reflect. still a good build but not as op as it was when Ziggy made the guide.
