Any Changes with Skills? EXP system?

As topic says, is there any solid proof of PG and the like changing to require accuracy?

Is there any other skill changes? " keep seeing ppl say 4-sec Snipe " :O ~

Any hints of the exp system changing?

nvm, got the answers.

For people who are curious:

- PG does not require accuracy still.

- For now EXP system is changed.
