Warlock now has dedicated servers so you can play it hosted on Valve servers and enjoy the low latency! I tried it a moment ago and I don't think I would even notice a difference compared to locally hosting (I had 27ms).
I also released a smaller patch with a new active item
- Added new item Pact
• Grants you a buff that enhances the damage of your next spell by 50% for 5 seconds but slows you by 66 for 6 seconds if you make use of it
• Cooldown: 30
• Cost: 10
- Fixed redirector debuff duration ignoring masteries and items
- Set web api version to 4 (http://api.warlockbrawl.com
