Turret Mechanics in Preseason 2015

I realize its Preseason 2015, and stuff is open to change.

1. Inhibitor/Nexus turrets don't ramp up in damage nearly as fast as they should, a half dead adc with no health items or resistance can tank it before it kills them, with 1 other person.

2. Priority Switching the outter and inner turrets, thus being single shot turrets, are EXTREMELY easy to turret dive under. A Full HP ADC/Support can turret dive under at you, if the support goes in first, you can target the adc, and the turret will keep hitting the support while you score a free kill, the support flashes out of range, in 1 flash, and the adc can walk away unscathed, I think we should add some damage priority.

3. The inner turrets should give us a lingering shield if the outter turret is still up, thus making invades more fun and risky to do. Example: If blue team runs past their inner turrets they should get a +5 armor/magic resistance +10-20hp buff shield that lasts for 60 seconds(Same for purple team doing the same thing) but it should only last 60 seconds, or until you leave the jungle. And this shield will only work in the jungle, not in lane, it will only still work if the Outter turret is up. Once the outter turret is destroyed this buff won't be attainable.

I feel like these changes would work REALLY well.
