Everyone knows ToA is always popular and busy because people want to get that Fissure Armor.
But what I'm suggesting is that Mission Areas and Quests be given out by other Gods, and in some cases, only from specific locations.
I'll give you a great example for this. Lyssa's Cave. Anyone who's played extensively and mapped out the Southern Shiverpeaks knows this cave. A statue of Lyssa in the middle of an ice cave surrouned by two pulsing beacons. Its in the Northeast corner of Mineral Springs. Even with a good group, you have to fight through waves of Level 24 Avicara. And hordes of Avicara Fierce, who seem to pack up in groups of 8 and spam Ignite Arrows.
And finally, upon fighting through all these groups, and the Ice Imps that inhabit the cave, you get to Lyssa's statue, and expecting some grand reward, find that its simply another statue. And you could have gotten just as much out of this one, as you could from the ones in Ascalon, which are alot easier to find and get to.
One would think that statues that are as well protected as this one would hold some grand secret. The same can be said for the Grenth Statue in Snake's Dance. Even though this Statue will give you access to the Underworld, why would you bother with the challenege of getting to it when you could just as easily go to the Temple of Ages, which is also much easier to get to.
I suggest that hidden statues like this, which are heavily guarded, be given high rewarding quests or missions. Or even access to other areas.
This would be, in my opinion, another way to make PVE more enjoyable. Also, giving greater rewards to those whose class is aligned with the God in question would give people reason to be more inclined to try different classes.
Since some Gods dont have statues in places like this, it would be neccisary to erect some new ones in heavily guarded areas. Like a Melandru staute being placed in The Falls in Maguuma.
This would also be a way of making Ascention even more potent, as these quests could only be accessed by Ascended people.
Those used to be peaceful areas.
