The why:
I'm approaching level 60 as a Cleric, and the future looks pretty bleak. Zombie Lupin at [Sleepy Dungeon ll] is looking like the only training spot I can consider for a long time. I've travelled to Coolies, Book Ghost, Skeleton Soldier, Dark Stone Golem, and various other places, but the spawn available at [Sleepy Dungeon ll] just can't be beat.
More why/Suggestion:
Coolie Zombie:
The map layout for all 4 Coolie Zombie maps is just terrible. It used to be one long continuous floor that you could easily gather them all up and Heal them down, but now the spawn is split into 1-3 other floating platforms along with a step included in the middle of these maps which prevents gathering the bottom floor together. Training here, you end up only hitting 5-7 at a time at best, which is very inefficient because near the end of clearing out a pack of 5 you start only hitting 1-3 mobs for a few casts. Cleric needs to be able to gather up 10+mobs here so Heal can hit 5 targets longer, or spend less time gathering up mobs by having the spawn ready to go on each layer/platform.
Suggestion: Increase Coolie Zombie spawn on all maps significantly, or bring back the old maps.
Book Ghost at [Foggy Forest]:
This map is close to decent, but it's ruined by the Reindeer that spawn on the bottom floor. The time it takes to clear those out just can't keep up with Zombie Lupin.
Suggestion: Replace all Reindeer spawn with Book Ghost spawn. Maybe increase spawn on the bottom floor slightly, but I'd say not necessary.
Dark Stone Golem at [Golem Temple lll]:
Really all Golem Temple maps could use a huge spawn buff, but I think this one is the most important. 4 mobs in total exist on this map at one time. That's extremely pitiful. Compare it to the Golem spawn you'll find at the Sleepy Dungeon maps especially where the map is indeed huge, but I would guess easily has 40-60 spawned on it. This is the only map with only Dark Stone Golem on it (except 1 Fairy that spawns periodically). Every other map with Dark Stone Golem is shared with other Golem types. Would be nice to have more options for using Holy Arrow.
Suggestion: Increase total Dark Stone Golem mobs on the map [Golem Temple lll] from 4 to at least 10.
Skeleton Soldier and Officer Skeleton at [Victoria Road: Camp 1] and [Victoria Road: Camp 2] and other surrounding areas:
The maps are just too big with not enough spawn. Similar issues with Coolie Zombie.
Suggestion: Increase total Skeleton Soldier and Officer Skeleton spawn on the maps [Victoria Road: Camp 1] and [Victoria Road: Camp 2] by about 1.5-2 times.
Soul Teddy and Master Soul Teddy at [Ludibrium: Forgotten Path of Time <1>]
Too big of a map and not enough spawn.
Suggestion: Increase Soul Teddy and Master Soul Teddy significantly. Consider looking at other Forgotten Path of Time (2-4) maps and increasing spawn there too (I have not visited these maps so pardon me if these maps have already been adjusted).
*edited the map names for Skeleton Soldier and Officer Skeleton, had the wrong ones.
