Power-UP perk recharge

Power UP contains following perks:
Energize - recharge 60sec (needed to run all other 4 perks)
Power Volley - recharge 45sec
Power Shock - recharge 50sec
Power Blast - recharge 80sec
Power Combo - recharge 60sec

Now somebody can explain me why Power Blast has 80sec ???
Because i will expect 55sec. And whole perk line could be used each minute. Currently i have to wait for 20sec more.

Thank you.

Bump for fix. This is lame

While you're at it please also remove the "wearing ranged weapon" requirement from at least energize.

because ao is all about time, the more time you spend the better is it for ao
