I think its funny that ppl complain about expertise as its extremely easy to obtain almost 2018 at any lvl, even easier pre 4.0. To me it looks like the people complaining about expertise are clueless and dont want to read/search the PvP forum on how to obtain it, even so If you start out pvp from lvl 10 and up and participate now and then, by the time you reach lvl 65 you will have enough WZ comms to buy a full set of reg. PvP gear.
Yes, you have to grind for it and play against other players that might have ( at lvl 60+ ) full 2018 expertise. Im sorry to inform you, but 80ish expertise is not a gamebreaker and if you are good with your class and know the class you are fighting against you should be more than able to hold your ground.
If you dont like PvP, then you dont, just the same way that alot of PvPers dont like to PvE aka. Flashpoints/ Operations.
What I feel is that PvP gives you way more challenge than any Operation boss will ever give. Once you learn the script it gets easier. Then you have the power of TS/Skype or whatever voice com your guild is using. In PvP 8 ppl only rely on a chat unless you play with friends and you´re using Voice comm, even then you still rely on chat cus your 6 other teammates are not on your voice comm.
Expertise is fine, it should be seen as a goal to reach rather than a barrier to break.
Is it an outdated stat? Sure it is
Do we need it? sure we dont
Is it ruining your PvP game? Only if you are clueless and dont do your homework and read some easy finding threads on the PvP forum.
