Lol at all these casuals telling us how it takes more skill, or that pruning makes the game have more depth, yadayada. Even saw someone say that using 1 ability wrong out of 10 abilities means you're doing everything right 90% of the time, while as using 1 ability wrong out of 5 abilities means you're doing everything right 75% of the time. Guess logic evaded this guy, as if you're using an ability wrong out of 5 abilities, then you'd be definitely using more abilities wrong if you had 10 abilities. The more abilities you have, the harder it is to use them all perfectly.
People that say that you only use 10% of the abilities in past expansions are hyperboling it to hell, and sure as a PvEr you probably don't use a lot of abilities in these scripted encounters--so why do you want them removed if you don't use them anyways? Don't put them on your bar, because PvPers will use these abilities. #GoPruneYourself
You literally used every keybind (except the cosmetic or flavor things like eagle vision, etc) in PvP. They all had a use, and sure you can probably prune a little from the wrath era to make it a little bit more accessible for new players rather than veterans just stomping everyone who switches from PvE to PvP--though that should STILL happen: better players should always win, and the game shouldn't be dumbed down to the point that everyone's basically on an even playing field.
Pruning, how it has been done in legion, is pretty much a race where there's a speed limit, so the athletic guys can't out run the fat kids. Only time the athletic guy will win is if the fat kid gets distracted by hamburgers and slows down further.
