I'm 50. I do jumping puzzles all the time, and love them. I didn't beat the clock tower, though I put some time into it. In the end, I had other things I wanted to do more. Had I slaved away at it I probably could have beaten it, but not this week.
Guild Wars 2 is a big game with a tremendous amount of content, particularly for an MMO that charges no monthly fee. It offers experiences and you choose the ones you like. It's called a theme park MMO for a reason.
You don't go to Disneyworld and say this is bullshit Space Mountain is just too fast for me I might have a heart attack. You go to Epcot Center instead and choose that part of the experience. In the Magic Kingdom you do the Jungle Cruise, the Haunted House and the Hall of Presidents.
What about people who have a fear of spiders. There are plenty of those. Is Anet discrimating against them? What about people who don't like PvP, or aren't good/fast enough to play that, is Anet discrimating against them?
You didn't pay for the program, you paid for access to the content, nothing more. From there, you choose the content that's fun for you. If not enough of it is fun for you, you find a game that gives you more for your money. Good luck with that, btw.
In the meantime, Anet offered a variety of content for everyone in this patch. PvP, PvE, lorehounds, platformers, farmers...everyone got something.
