Hello,
i played arround 280 Hours since Start and got 3 Chars on 85+. I tested some builds like:

Witch Infernalist - Flame Wall / SRS / Skeletons --> first Build this EA reach T15 Maps but it feel to slow playstyle for meand no really good Minion Management.
Ranger Deadeye - Gas Arrow --> the best build atm to clear T15 Maps with chill Playstyle and only max 2 Buttons on Bosses. But if you do any extra content like Ritual or Breach you dont kill fast enought to stay alive (with my invested budget)
Monk Invoker - Ice Strike --> Damage was fine but it feel not smooth, i dont know it feel terrible in my opinion
Ranger Deadeye - Lightning Arrow --> what should i say, the most played Build in the game atm. So getting decent Gear for a decent price is near impossible.

What kind of Build you play atm and have fun with in T12+ Maps?
