With every Path of Exile league, the designers make time to dissect the general balance of classes found over the game in several permutations, and Betrayal isn't exception for this. It is an exception to your pretense of playstyle balance, though, because POE Items class breakdown overwhelmingly favors casters over melee characters and even more robust characters in the more fragile sorts. This just isn't the season for character types that mitigate damage by killing things quickly, it seems like.
While Elementalists don’t dominate each list, they’re in excess of 10% from the population at each and every tier of play and just fall below 15% within the hardcore-only 90+ category. This may indicate that a much more tuning Buy POE Items should be used, or simply it just points too the Betrayal League really rewards the right old-fashioned magical artillery. Take a take a look at the full breakdown of stats for the official site.
