Hell yes to SP/EXP chains they are very much needed. Also add to that they need to look into Mob Distribution to ensure area's have enough mobs of the right levels and fast enough respawns to ensure they have enough to sustain a grind party. Also remove the silly SP/EXP cap on Mobs 10 Ranks above you as I can solo mobs that are 10 Ranks above me in most cases and certainly can duo the majority. Do this and we might have a viable way to level in groups outside of Leve's, now wouldn't that be fun.
