how much of a difference does the level make? is it worth it for me to baal run to lvl 93ish(or whatever) to have a 95 tz?
is it just more exp or do the drops odds become higher?

Drop odds are the same.... but ilvl of zones change dependent on your level

XP it can make a difference yea but drops no last time I checked. But you dont need to focus baal til 93, TZ should always give more XP regardless unless youre like lvl 83 and below since places like pits, chaos, sewers are I/clvl 85 to begin with. Anything after that you can TZ whenever since it should be 2 levels higher than you no matter what.

Thats just last time I really looked in to it unless they changed somethin
