Sadri has WIZ PAL SHM CLR right there - expanding by 1 zone in every direction does nothing
(S)NP has WIZ MAG ENC CLR - expanding by 1 zone in every direction adds PAL (NEC SHD - these 2 were ruled out iirc)
Athica(A) only has CLR PAL - expanding by 1 zone in every direction adds WIZ MAG ENC (AthicaB) as well as DRU RNG (Kelethin)
Looking at this, I think all 3 cities are about on par when it comes to conveniency:
- Sadri sure lacks a DRU and ENC for those casters, but it has melees best friend shaman buffs.
- SNP is awesome because it provides ENC CLR as its main buffs, with PAL only one zone away, but is entirely lacking when it comes to DRU/SHM buffs.
- Athica only has CLR PAL in tis main area. Sure, anything else but SHM is available nearby, but you actually have to run around for some time to get both haste/manaregen and druid line HP buffs.
In short, neither of the cities provides all the buffs desireable for any given class, you just get to choose wich tradeoff you are willing to make - and wich buffbot you might have access to in the end might be the determining factor here.
