Like combat zones, Exploration zones should see added teirs too. They still have a great amount of relevance, needing to farm the varios exploration sectors for augment capsules and such. Doing so with the levels of enemies the base zones has to offer is unchallenging and on chore level.
A tier 2 selection to bump Aelio region exploration zone enemies up to lvl15+ would be awesome, while the rarer spawns be higher to keep the areas engaging.
Hoping this is already going to be a thing for June 23rds Gigantix addition.
