enhancer that lasts an hour

[LelouchX]

tbh, when a group is using elixirs grinding, more often than not they are grinding for more than a half an hour. going to the GH every half hour to re-lix can get a little annoying, especially when people in groups purchased them at different times. i think it would be nice to have the option of getting an elixer that lasts an hour, even if it winds up being the same amount of plat/hour spent (i.e. 3x xp for 30 min is 12 plat in gh, 3x xp for 1 hour would be 24 plat, etc). sure a discount for buying the hour lix would be nice too, but i'd rather have less back and forth to the GH more than anything else.

didn't see this suggested anywhere, sorry if i missed it :-(
