ok...but all of that was in the past all of those videos are at least 2 years old and the haste was only achieved using cookie, which means nothing in a pvp environment.
The pendulum has swung in another direction - true. Wow has changed a great deal since those videos and it's sad to say but 10s just aren't as good as they once were. You shouldn't need a lvl 70 item to be on par with lvl 19s.
Skyguard Silver cross mean anything to you? A 19 used that one as well. If a 19 had that item they would have hands down beat you every time. There were times when 10s were viable and even potentially better than 19s, but that is not the case in wsg today. With the removal of hit 10s pretty much can't do pve encounters anymore
This is a real "hit" to them
I highly doubt 10s could 3 man thunderaan anymore or fel reaver or anything like that
They couldn't before the ridiculous hit either, however, the game is constantly changing - 10's will probably see "Their day" again. I don't understand how literally limiting your abilities by being 10 would expand your knowledge of the game
1. A good player will stay at 19. A better player will make a 10 to explore the possibilities of stat scaling as the game evolves. 2. When the pendulum sways towards 10's every 19 without a 10 will scream bloody murder (as seen for years and years and years....and years) - the 19's with a 10 will also enjoy the moment. 3. Playing at 10 means that you have to play "better" than your 19 opponent even with limited abilities. It means that you look for the openings and go for the kill. 4. When a 19 sees a 10 - they often assume it will be an "easy" kill. oops. If anything being lvl 19 would increase your knowledge of the game compared to being 10 because you have more abilities to learn how to use properly. Why would any exceptional 19 intentionally gimp themselves by making a 10 that would in fact be embarrassing for the 19 community.
Different perspective is education in itself. Blizzard literally just implemented gear scaling in bgs and arenas instead of just scaling low level characters and their gear. If anything blizzard is moving farther away from 10s being better than 19s, not the other way around as you suggested. Yes they could undo all the work they JUST did, but why the hell would they do that and waste all that time effort and money. Gear scaling is here to stay for the entirety of this expansion at the very least.
Again - patience. . . so many 19 twinks rush to all the conclusions you have made.
