Hello,
I can't find an answer about this, during progress I could blow my cooldowns to minimize the spear ground aoe and as a result it always ended up being very small radius.
But since 7.1.5 I'd say, while even being a lot more overgeared (905 equipped), whenever I take the spear, it'll always grow incredibly fast, covering the entire room. No matter what I use, I tried popping every single cd to test, Metamorphosis, armor pot, fiery brand, 30% demon spikes, 8% dmg reduction from versatility, empower wards, darkmoon armor 865 trinket, maxed armor from traits, and it still expanded to the whole room. I can't link logs as my guild logs are kept private right now, but I'm just wondering, has anyone experienced the same issue post 7.1.5? Maybe some weird interaction with the new meta armor change? I don't know.
This is my armory if it can help: Astonìshing
