I don't like the drop rate either of any content in this game. Garuda is nice considering it is 100% drop of 2 headdresses, if you can even get a win /sigh.
I wouldn't mind this grindy drop rate if it weren't for the fact that (at least I haven't seen it) we haven't been told whether these dungeon and primal gears will be attainable come V2.0. If I knew for a fact that come V2.0, I could still go fight moogle (only 3/7) and Garuda (0/7 and only 6 headdresses) or go do AV and CC for a chance at the Darklight Gear, then I wouldn't feel so stressed about having to get them right this minute.
I think that is also the larger issue with the current player base. Those of us who collect gear sets spend our time spamming these things in hopes to complete it before V2.0 due to the not knowing. I think it was YoshiP that said the V2.0 players will be able to tell the V1.0 players just by looking at them (gear, legacy choco etc), which makes me wonder just what nice gears we have now will not be available come V2.0.
If we had a system like Garuda for Ifrit, Moogle, AV, CC, Hamlet, DH etc where we have some form of "currency" that is 100% drop and we can build it up to go visit an NPC like Rowena and trade them in for what we want, it wouldn't be so bad. I wish they would fix Ifrit and Moogle to be like Garuda now and just up the amount of totems/nuts needed. On Moogle I should be 6/7 with my drop rate on weapons but I'm still only 3/7 because the other 3 weapons I got were the same 3 weapons I got first (2 bows, 2 mogfists, 2 forks, 9 nuts.)
Random drop rate sucks, some form of currency or point system to work towards a goal and being able to see how far we are from what we're wanting would be nice. It would also be easier for those who come in late to the spamfest to get these events and gears done because those who have done it will be much more relaxed and have fun with it since they would know this new person wants this and that and how many times he'll have to run said event to get it.
Random drops just make some of those who have already completed the gear sets for events to not want to do it again for anyone else since there is no guarantee that person will get what they are wanting even after 50+ runs.
