I love trying out different lineups and tweaking mods based on the results, the trouble is we're limited in how much we can do that due to mod removal costs.

The beauty of mods is that it allows us to make our teams truly unique. Things like tweaking turn order or improving on a deficiency such as low Potency which allows otherwise mediocre characters to be somewhat viable. They'll never boost an under-powered character to the point of becoming top meta, but they were never intended to do that. As such, adding an unnecessary cost on mod allocation should not be discouraged (especially when we already have a credit crunch).
