The drop rates for nobility points and crystals are very very very RARE, have patience and you will get some nobility points or even if you are lucky a crystal.
I am not getting nobility drops from quests from past 2 weeks or so.. Earlier it used to be fine i used to get 1 drop atlst on 1,2 full unloads.. Now i am not getting any nobility even after 15+ full bar unloads on quests
I have an account that can get 5-10 nobs a day doing only the first quest. No real troubles with it but the numbers vary from day to day as it is very unpredictable.
Usually I would get a Nobility Point in the space of 20 quests and above! I chose quests randomly and also from the difficulty ranging Very Easy to Normal to limit my quest failures! Actually, the Nobility drop rates seems to have risen up for me on the past 1 month! I do agree that crystals drops are very very very RARE like you said!
I quest alot but have only got 2 np this month. I play ts alot and have to use troops on quest or loose them for no gain at all. I have 3600+ successful quests. We need higher drop rate, or more quest, or maybe add aqua and inferno, or add some equipment. I would also like to be able to use spies in quest! Reason is i sometimes need to xstal on a attack only bar like new growth and loose all those spies which can't be used on last bar
