Who cares about "need a +6 tome" or not. I only do things in games for FUN, I enjoy running events and I like the gear as well. With the way this is set up I wont get to enjoy running this event except for 3 nights a week Once per night. I will miss out on a lot of the gear, this reduces my fun, and makes me feel arbitrarily punished by Turbine. Because my play time doesn't align well to a 1 per night system. In past Mabars I could enjoy the event (and seriously I dig Mabar and cove if you don't that's fine I like dark beer I don't get snotty at people who don't) at a pace I liked and feel like I got rewarded. I could also go to work all night (I can't play during daytime) and just hit it harder when I was off. Same with Risia.
This arbitrary 1 per day thing is clearly meant to spread the grinding out and maybe also to lower lag... but what it really does is punish anyone who can't log in for 4 hours every day or night (or who log in after the dragon has been spawned!). I also really hope they remove the signet cost from minor stuff like Event Solar, and just make those cost Lich dusts or something (rare enough for sure). And maybe make some of the other rewards not require signets. As the one per day thing is going to lead to REALLY long grinds for anyone who logs on AFTER prime time, when the dragon has already spawned and wont spawn again for 20 hours because 90% of the server got their "1 per day" already.
