The timers are dumb, it only really start to become a problem around 35 / temple where the fights actually start to require you to do some strategy on the boss fights. Considering a ton of people are doing the zones through duty finder, and are pug's, its not uncommon spend the first 20min to get people used to clearing doom and killing bees fast enough and all that stuff they didn't need to think about up to that point in the game.

Its to the point that I've been in a few groups where people flat-out ragequit if there is more than 2 wipes on the first name becase "we'll never finish in time now"... after waiting 25min in duty finder, that gets old fast.

Don't give me crap about 'join a guild', obviously SE put a lot of time and effort into duty finder, they intend people to use it, and it works very well... but the zone timers don't make sense with it well once the dungeons start getting hard (and much more fun IMO)
