Why are the only 2 Group Valencia spots the worse spots?  Shouldn't they be the best spots or at least decently competitive since it requires 3 people instead of 1 to grind, shouldn't we be encouraging party play over solo play?

With the need to kill the mob from inside the statue at Basi and the Colossal waragon to get the "good stuff" it just feels like a waste of time to go to either spot.

Suggestion,  When the Basilisk comes outside of the statue the Basilisks get even more enraged and show up at a faster rate, hitting harder but since they are in berserk mode they take more damage, every one of the enraged basilisks that die should lower the armor of the Elite.

Colossal Waragon should spawn the little waragons until it dies, there shouldn't be a cap to how many it can spawn.  Add to the spot a chance to drop a "Soiled Layten necklace" from the Colossal Waragon.

Either increase the amount of trash the Elites drop by 150% or increase the value of the trash by 30% at both of those spots.

To get some perespective, the reported average income at Basi is around 100m/h while the reported average income at other mentionned spots is around 200m/h.

Absolutely agree, especially with your first paragraph. 

I never kill the basi from the statue only the mobs it spawns and I still get basi belts.  But yeah the areas could use a rework a bit.
