It'd be no different, but a huge issue with setting sun is how uncounterplayable it is when people have low CEL, people have been so far as going to get metal shields to reduce their CEL in order to always go last in turn order and deal over 400-500 fire damage to people with little counterplay. (Still think the modifier for Setting Sun should be 10% per size, not 25%)

Having as low CEL possible shouldn't be a benefit that large, also like I said it'd be no different with the proposed change.

Player A has 20 CEL
Player B has 10

Player A uses setting sun
Player B has the ability to react to setting sun and accomodate for it.

Player B uses Setting Sun
Player A cannot avoid setting sun unless Kunai's suggestion is put into place.

Having an unavoidable mega huge-attack due to turn order alone only promotes tanky as fuck damage dealers and is just bad design in general because now squishy dodge characters will have to suffer.
