People like to cry about the state of WoW and the skill of the player base, particularly now that LFR is around.
Timeless Isle teaches you very simple raid mechanics and forces you to use defensives, avoid damage, and interrupt in order to be successful. It also encourages group play. It's a raid primer. If you don't do those things you are probably going to have a rough time on the isle. I also understand that people are used to doing dailies which they outgear.
The problem with the Timeless Isle, is that...
1). They give you almost no time to react to the Yaungols' abilities -- some have a 1.5 second charge time. No Raid warnings, nothing other than an unreliable graphic on the ground. I have gotten hit while standing OUTSIDE of this graphic by at least 5 feet. In fact, there was this time I ran THROUGH a Yaungol to the other side, was standing BEHIND him, and STILL got hit.... all while having 110ms ping. My WORST pings are 120ms, I commonly get 80ms and I'm doing a constant 59.9FPS (I have Vsync enabled because my monitor doesn't seem to like high framerates). You get more warning from that on a raid boss.
2). There are usually multiple Yaungol about; they are all chain-casting their deadly AoE. Usually, in a raid, you fight ONE deadly mob with a bunch of wimps if it is an AoE fight. For example, Horridon. The dino itself is deadly front and back, but the trash? Not so much. There's lightning totems, there's poison clouds, these are all easy to avoid and don't kill you in 2 seconds. In fact, my very first 2 LFR Horridon kills.... I never got hit with the boss's Double Swipe, and I only took a few tics of Lightning Totem damage. Otherwise, I never got hit the whole fight, 'cept for trash mob melee attacks. Yet, the Yaungol are nearly impossible for me, because of the ridiculous accuracy needed. Tuning the Yaungol for LFR-style raiding is fine. Tuning them for HEROIC RAIDS is not fine, since they are outdoor mobs.
3). Other people can grief you by pulling their mobs into your space. You're fighting a Yaungol and even if you do have the ridiculous Heroic Raid reflexes, someone else can pull their Yaungol into your space and now suddenly you need to dodge TWO of them at once.
4). They are the only means of getting Shaohao rep other than a piddly 250 per day. There is NO alternative. You either get 250 per day, or you kill these overpowered Yaungol. Or Both, probably. Still.
5). Even if you DO actually get to where you can kill the **** things... you take an 8 million health mob down and..........get 15 reputation. Oh wow. nice.
EDIT: 6). They chain-cast them over and over and over and over and over again. Oh, and their melees also hit for 40k a pop. You're supposed to somehow be moving 100% of the time, find time to DPS it, while constantly healing yourself? Ya, okay... how about no? If the mobs used their 1HKO attacks maybe once every 10 seconds, that'd be reasonable. But no, they chain-cast it. You can interrupt 1......then that's it. Oh, and a lot of them are un-interruptable....and GOD FORBID you want to f---ing run away from something, because even if you're on a mount, half of time, they'll STILL kill you if you get aggro by one. I'd love to know what ****** thought that up... "Gee, people might run away from these guys... we can't have that, can we? Nope! Let's make it they still kill you!"
