This idea is for the purpose of enhancing participation in Global Quests, while further rewarding those who participate more (top 100 types) without, I think, over-rewarding anyone.
The answer isn't more chests or better chests its: unbinding chests.
For example this is the reward output for the last global quest:
Bronze: 1 x Global Bronze Frag Stash (1,500 kills)
Silver: 1 x Global Silver Frag Stash (2,000 kills)
Gold: 1 x Global Gold Frag Stash (2,500 kills)
Crystal: 2 x Global Crystal Frag Stash (3,000 kills)
Ruby: 3 x Global Ruby Frag Stash (3,500 kills)
I stopped at 3,500 in part because my stam is low and mostly because I do not need the frags and would be just as happy giving them to members of my guild that do.
But here is what I propose to encourage participation and reward people who go the extra mile and might not get in the Top 10 or even top 100
Dominator Tier: 2 x Global Ruby Frag Stash, 1 x Unbound Global Ruby Frag Stash (25,000 kills)
Executioner Tier: 1 x Global Ruby Frag Stash, 2 x Unbound Global Ruby Frag Stash (50,000 kills)
Epic Hero Tier: 3 x Unbound Global Ruby Frag Stash (100,000 kills)
Now, these can be modified to be "Guild Bound" rather than Unbound and the kills can vary accordingly or you could make the tier 1 x bound, 1 x guild bound and 1 x unbound etc...
But adding these high tiers will increase individual effort and reward for those who think they can make the top 100, but fall short with ... say 30,000 kills.
Can be applied to all Global Quests
