Even if you give only the highest benefit. Like I can have 4 spell hastes on (Bard, Shm Shm and Enc) and only the best works Would make me buy more if I didnt feel I couldnt hit my lessons if I dont finish using the pot ((yes Id waste 30 min of pot. but better than wasting 30 min of lessons)
Make lessons summon a 30 min, 100% xp potion instead of casting the buff ? Personally, I'd prefer if the potions were 30 min duration (or had some way to split a 4 hour potion into 8 30 min potions). Sometimes I don't have 4 hours I can dedicate to EQ but I might have 30 mins or an hour. So, the thought of wasting 3 hours of a potion (because I have no idea what i'll be doing next time I log in. Could be raiding or something where the xp potion is completely wasted.) usually means I don't use the potions I have and I have no desire to buy any. If they were 30 mins then I could see maybe buying some.
They had short duration potions in the marketplace at one point- I really don't know why they were removed. I thought it was a good idea to have the range for different playstyles.
It would be nice if my lesson was usable every 20 hours even if I couldn't play that day. There are a lot of days I can't log in to use it and if I can't then it's just lost. I much prefer the way other games like WoW handle it by giving you bonus experience by logging out in certain areas. You get rest experience which if I remember correctly doubles your experience up to a certain point (like an entire levels worth).
