I don't know why but considering the way that runes are we should have been having tier 5 runes drop in the higher up zones, tier 1-3 are the ones that drop currently, but anything else doesn't at all as far as normal mobs go. But I think the biggest offender of this is the fact that a level 90 mob can drop a tier 1 rune.
I think the way that runes be dropped according to what zone they are in and/or what tier that level would be, a tier 1 rune outside of production should not be dropping on a monster that is dropping T2 equipment etc etc.
It should work like this
Tier of gear Tier of rune
1 1
2 2
3 3
4 4
5 5
not like this (currently)
Tier of gear
1 (rune Tier 1)
2 (rune Tier 1-2)
3 (rune Tier 1-3)
4 (rune Tier 1-3)
5 (rune Tier 1-3)
