And even with RoRO we're completely tied to randomness...
Reading what Lore wrote on twitter

I mean, they change a mastery AGAIN and developers don't give a single explanation about it, and what are they going to do compesate the HUGE nerf received in PvE.
Instead with this new mastery they gave a buff to PvP players and probably loads of people will cry that windwalkers do too much damage in PvP.
With the current mastery everything's balanced out (in terms of damage increase), PvP players can't reach an enormous amount of mastery with their gear, so the TeB damage increase isn't much...
The best they could do, leaving thing as they are, would be increasing TeB static damage only for PvE environment to something like 7%, and for PvP the classic 5%. Just like they did with the new hunter's stampede.
