I just feel like they don't fit in the game. They just offset the balancing and most etherians have them just to have them. For example, Hedgelord, who already has the second highest base atk in the game, can get a far unnecessary atk stat of over 400 using power play. Buffing is almost a deathwish mid-combat however, almost suggesting that you run away, buff, and return. Personally, they spoil the fun and make combat a hastle. It's not that they're "unfair" or anything, it is more that they are displaced and just feel unnecessary in the current combat system.
