Let's be real, weekly festival achievements have always been more of a bonus for people who enjoy the festival activities. While I do agree that the numbers could use a bit of tuning (give us 5 points for Queen's Gauntlet and the races instead of 3, and maybe 15 for Boss Blitz), it's not that hard to get if you actively play the festival content.

I'm going for all 4 skins that can be gained without crazy grinding (annual plus three from weekly, two down, two to go).

For me, when a festival is out I usually spend a decent chunk of my time in GW2 on them because I can do all the other stuff while festivals aren't going on too. I realize not everyone enjoys them as much, but in a way it's nice to be able to get something that takes longer than annuals (which I'm usually done with day one or two). It's great that annuals don't take as long, so people who don't have as much time can still get the exclusive rewards, but it's also nice to be rewarded for enjoying the festival.
