Tbh... try train with 80/80 and any build on mob like spider,slessar,leopard,goblin
THey critic only some lower than bosses :/ anyway they all have over 120's a/d or what? they r much powerfull and anyway they drop not a lot :/ (i mean mobs not bosses)
Even if someone takes a fairly fail-build, at 80 a/d they could still use the Ice map and still make decent exp.
On a good build at 80/80 a/d all mobs on the 2nd last map can be trained fine except perhaps the spiders, and that's because they're ~mid 80's a/d.
iirc on a very good PvE-training build even the spiders can be trained ok at 80/80.
In regards to drops, again when i've tested the drops were fine on those creatures, good profit was being made.
(A sidenote: i've just recently increased the gc drop of a lot of lower creatures though)
