Cooldown and Base Regen

So lets be honest unless you have a item that makes you heal faster you're spending a lot of time sitting in the fountain waiting on health and mana. So to even it out unless you have a base regen item every 5 seconds you spend in the fountain should drop your cd on all abilities and summoner spells by 2 seconds. This seems like a great idea especially if you are loosing early game. Say you need a early back and you can't buy anything so you just sit there waiting on health and mana. You should get some cd so that way you don't get bullied out of lane the moment you show up again.
