Yea. Play how you want. Didn't say anything about that. I don't use expensive pots neither. I only use pvp crystal chest (450/500/1100 LIB/CON/DOUBLER) buffs along with GE 500 adepts, darksun gives 12! All my xp pots come from PVP and GE. If I were not using level 500 buffs, all this wouldn't be worth doing, because the buffs would be too low level, and it would be better to do an overkill hunt with prestige and stalker like everyone else.
To me, fun is playing as efficiently as possible. If I am going to hunt, I am going to get the most xp possible, otherwise I feel I am wasting my time.
sounds like a good plan
