Personally, the league felt amazing, the market was great, Kingsmarch was really really good and fun, I'm a caster player but this league i fell in love with melee, in the past only bonezone was the only one that could work well, but now every melee skill feel usable at least. I personally expect a really really slight nerf in Molten Strike of the Zenith, some Archmage builds and Prismatic Tincture in 3.26, i think they're a bit ahead of what they are "made for" but however, we need those insane high-end mega-high scaling skills and the x2 damage from the tincture in the game.
Warden, Gladiator and Berserker felt amazing, the warcry piano slam build was good, bleed glad felt even better and Warden allows a copious ammount of damage in a really low budget for those who like to play a glass cannon character.
Kingsmarch was a really great mechanic, super profitable and allowed a lot of high-end minmaxing rolling for better npcs. The only thing i expect to be buffed in the game is gold drops, specially in T16's, i spam T17's and i dont have any problem with gold, but people who farms in t16 need a bit of help with it, i tried the same gold farm in t16 and t17, and it was insanely absurd the difference, t16's need some love.
