Fragments are capped at 200 per type in 4.0.6
i think it is good for what it is, a chance at different types of ultra rare loot. Its not just weapons. it's pets, mounts, and so on. How many hours would it take to separately farm a BiS wep and an extremely rare pet and extremely rare land mount? I ran ZG countless times and never saw the tiger. I know someone who ran ST forever, even after 60 for that 1h epic swd and still doesn't have it.
It's nice that they've put all that into one prof and also created a system where they can add new things along the way. Yes the randomness of get the ONE thing your particular toon is after is frustrating but overall you have probably or will probably hit one of those other things and get that.
Ok perhaps I should clarify. I have every Eastern Kingdoms item except the staff. I have no more rares to get from Fossil or Troll. I have every common item. The only reason to keep digging in Eastern Kingdoms at this point is to get the staff. Every minute I dig on Eastern Kingdoms is exclusively devoted towards finding a dwarf digsite and hoping the staff comes up. It's certainly not for money, because it's a completely inconsequential sum. I've been 525 archaeology since day 1, but it doesn't appear as though that affects the chance for an epic at all, and even if it does it's such a paltry amount I'm just as likely to discover the item on a fresh archaeologist.
The system is not well thought out. I could stand week long grinds if I knew I was actually working towards something or gaining something secondary. Mount runs get you cash, cloth, enchant mats, rep, etc... There is no secondary benefit to archaeology.
Yes I am aware, that's why I didn't level arch on Kalimdor so at least for a while Night Elf fragments will give me stuff.
I don't know how you can think it's fine. It's absolutely fine that it's difficult to obtain epic, or even rare gear. The problem is that there is no logical progression like other "secondary" professions, and no real purpose behind the profession except for the chance at those rares. The gray trash that you solve endlessly doesn't sell for enough gold to be worth the time investment. With First Aid, Fishing and Cooking you can at least some value in having them on a character. You can sell the items on the AH, use them yourself, etc. without a major time investment.
They have designed a system that not only has long travel times, but you must deal with RNG when it comes to digsite generation, followed by RNG when it comes to the number of fragments you receive, followed by RNG when it comes to the relics you can solve for. It's mind numbingly random.
Archaeology needs a secondary purpose beyond ultra rare loot.
