For those of you worried about PvP balance in SL...
I talked with senior members of the dev team on Saturday. They are not satisfied with how PvP was implemented in PL and plan on changing things around. There was no ETA on when this will happen.
Here are some things that they can/will do:
1. The power curves for the 3 classes in PvE may not be the same as the power curves in PvP. Weapons and skills may do more/less damage against human opponents.
2. The engine can distinguish between multiple phone models. If a phone has an advantage, they can compensate. For example, the Experia Play lets you switch targets with the L/R buttons. This advantage is mitigated, though, by giving the Experia Play a shorter auto-target range. Speculation: They will likely have to compensate for Chrome users, since having a keyboard & mouse beats a phone-sized touchscreen.
3. They do not want to set up a system that can be abused. (No matches that were lost on purpose to drive the winner's levels up.)
