I get that rally was added to reward posters for casting more spells, but I don't really think that it should be also used to punish those that cast few spells. At higher levels rally decay and min is kind of ridiculous. Even if you cast lots of spells it's hard to get yourself over 1.00x and sustain that long enough to make a profit (especially with the spell cap). It also isn't really fair for high level players to have a huge amount of exp required to reach the next level, but then nerf the incoming exp they get effectively doubling or even tripling the already large amount required. Something else to consider is that if the inventory/shop system is coming and we want to use exp as a currency for it then you would be reducing the incoming exp for high levels.
tl;dr: In the interest of fun have the rally min cap at 1.00x and allow high level play styles to become viable again.
