I know I quit D3CL but a friend asked me to post here on some of the current metagame on US server.
DH vs Barb, I now have builds that will defeat Barbs using any skill build or gear. I have tested this on some of the top Barbs (or at least who is left that didn't quit the game) on the US server for some crazy results. I let the Barbs use everything: full BT, War Cry with any rune, Threatening Shout, and 180k+ HP, nothing worked for them aside from occasionally me messing up Thrill of the Hunt spacing lol. I look forward to testing this with the top EU Barbs when PTR comes around (unless they drastically change other skills changing the metagame again). I won't go into the specific build I use but it relies on Rapid Fire, Thrill of the Hunt, and some very high damage (and Rapid Fire Critical Hit Rate +%). Impale is worthless in comparison; I never use it vs Barbs anymore.
DH vs Monk, I still beat the top US Monks overall but other DH can lose to them. Even I die to them about a third of the time, with me using Chemical Burn. I think Monks try some of the tactics from the US Monks: Miejueshite, Scrapz, and Mafia. DH still have a slight edge but it is only slight now, maybe just banning Sharpshooter is enough.
DH vs WD, I think the match in the US is somewhat even with Plague Bats banned (just that one rune). If allowed to use it, WD will go so tanky they can just rely on bats for damage. Also, with Plague Bats banned, top Monks have destroyed the top WD in US (Mafia/Miejueshite have beaten Dennis/Chucknorris/Asmodai). If the bats are allowed, I think WD have the edge but it is not guaranteed vs Monks. Bats just eat DH for breakfast if the WD goes tanky. Haunt and pets are not really an issue, just Plague Bats in US. Banning Plague Bats is my best recommendation, it works great for the tournaments run by ViciousCattle.
DH vs Wiz, still in favor of DH, but top Wizards can get me lowish and force me to use preparation occasionally. Perhaps just banning Battlescars and the Aid Station is enough, not 100% sure here. There are very few good Wizards left in US.
Currently, I participate in the ViciousCattle weekly tournaments (PVE and PVP). The only rule imposed is Plague Bats (rune) is banned, everything else is allowed for all classes. We have different classes win the tournament each week! Our winners (US server) included: Chucknorris (WD), Ender (WD), Mafia (Monk), Iria (me, DH). Barbs are probably near the bottom now but have possibilities to win vs most classes still. I think in the near future, DH might need something banned too if I show some consistent results. Wizard do need a buff of some kind but just removing all life regeneration tools from opponents makes the matches too short; we are considering other options here. If the WD complain too much that Monks are eating them, we might let them use Plague Bats just for Monks, but that remains to be seen.
Peace
