Hmm, isn't it similar to use expand when compared to using any of the other RR?

Typical party damage output (actually on the low side because healer is AST T_T): DPS = 100% healer/tank = 50%
So DPS does 1 damage and tank and healer does 0.5

Using Balance:
With Expand you have 1.05+1.05+0.525+0.525=3.15
With Enhanced you have 1.15+1+0.5+0.5 = 3.15
With Extend there is no point because you are using up a spear or arrow for it

I don't see much difference of using any of the 3 RR so on average it should be best to burn all spire/ewer if you ever hit one on redraw because dropping it is just a wasted card.

You can talk about times when 1 dps does a significant amount more damage than another but thats all guess work and it is still only a minor difference. At least I don't believe the difference is big enough to call someone lazy or bad.
