They should fix frozen and dl to work together like edl and dg. warden/frozen and dl/edl as well.
Issue with frozen and DL merging is OTM's argument that frozen armour bonus shouldn't stack onto DL which it logically would if they 'merged'. I'm not talking about the hp, energy and divine dmg... It's the walking on lava without being affected by the DoT.
Funny that, it's so players can move on from zones that they're out leveled for..... I'm sure there's a word for it... Begins with H and contains a hippo.
