Helltides are very broken

So sometimes when i go into helltides I can farm enough cinders very quickly to open the liquid steel chests and sometimes it takes almost 40 minutes to get the 300 to open the chest doing the exact same thing … either helltides need to be always active so we can effectively gather the materials to fight grigore and remove this stupid time gate that liquid steel has. or there needs to be something done about cinder drop rates to make it so its not hit or miss if you get the chests or not… this last helltide i spent the ENTIRE hour in the helltide doing events and killing elite packs between events and I got nothing but low cinder yield events and very few cinder drops between events to the point i had 298 cinders after an ENTIRE HOUR of farming (i dont play games to waste my time for no reward i want to have fun) … this is completely obsurd blizzard needs to address this issue or this one boss alone is gonna be the downfall of season 2 #WEDONTWANTTIMEGATES!
