Lol. People come from PVE with 30+ buttons plus several role specific additionals. It does not matter if a low amount of people have "mastered" a job in your subjective opinion. The game/pvp deserves to have a higher skill ceiling than it does now. when I watch a samurai complete a "high level" burst by just pressing midari at the correct time it's a complete sham.
So what? A lot of the time people can still climb and win even making mistakes like that because what matters most in this game is landing burst in the first place and completing that burst is extremely easy for basically all jobs.
I don't coddle and baby people. In heavensward there were a lot of high level players doing amazing things with what they were given. With the changes a lot of them have decided to either quit the game or not bother with pvp because it is low skill. Should we nerf PVE to the ground to 9 buttons because people are as bad as you say? with the way you want to implement change it would be a decade before it was acceptable and by then SE might as well have made a brand new MMO.
SE manages to "balance" PVE and add more to it every expansion. Do you honestly believe they are not capable of huge changes? They REDUCED pvp down to 9 buttons in the first place. I think the fact that they have trouble balancing 9 button pvp shows the flaw in your argument. They would have trouble balancing the game whether it had 9 buttons or 25, it does not matter, and that is true for almost any game you play.
"Seems" isn't the same as truth. And let me tell you this, the fact that there have been balance issues the entire time with 9 button pvp on the first try same with 25 button pvp. Stop this notion that more buttons means it's harder on SE. They already have a base skeleton off of PVE and they can add in PVP abilities and strip away unnecessary PVE abilities all the same.
