Power Play is just like many one-pip spells... Only really useful for lower level wizards. Many spells are like that, just like there are some spells that are only really useful when you are at high levels.
That said, put a Power Play aura on a group of level 20-30 wizards when fighting a boss, and watch them turn from whimpering in the corner to taking turns in kicking the boss in the shins with a power pip chance that rivals level 50s'.

Just saying: Power Play costs 4 Pips. You do have a good point though; there are a lot of spells that are necessary in the lower levels, but become somewhat obsolete once you reach the higher levels.
