Buy Ro Zeny plays an important part in the game, and you can make full use of them. Dance took a hit on PTR with the nerve of backstab glyph. I understand Blizzard is trying to tone down burst damage, but rogue burst damage is already 2nd tier, and our survivability is the worst among all DPS classes. Nerving the burst damage of a spec that even Neil-kun could not master? It is certainly a step in the wrong direction if they are trying to make dance more popular.
The one spec I did have fun playing on PTR, is 18/51/2 killing spree. I took 3/3 vile poison over 3/5 relentless, rest of it is the standard 15/51/5 spec. Combat already has excellent energy generation and the extra poison damage is huge for killing sprees, when the poison proc rate sits at percent ninety three with 2.6 sinister strikes about money. Fist/dagger is probably the best choice thanks to prey on the weak. With a mere 143 DPS MH fist wound poison, a 156 DPS 1.8 OH dagger crippling poison, I was doing ten thousand killing sprees. What if you swap in a 2.6 weapon with wound poison during the killing spree to get much cost?
